Established in 1934 as a small 

family business Lindapter has now 

become the market leader in 

steelwork fixings with a worldwide 

reputation; export accounting for 

an increasing portion of our 

business. Lindapter abides by 

a policy which includes strict 

adherence to quality control and EHS procedures; 

also offering first class customer service using state 

of the art equipment. Continual improvement of 

both products and policies ensures that Lindapter 

continues to be at the forefront in the marketplace. 

All enquiries are dealt with on an individual basis 

ensuring that customers receive the correct 

technical support together with project specific 

drawings in either 2D or 3D formats together with 

itemised parts list; all part of a free comprehensive 

service. 

For situations where standard products are just not 

enough the R & D facility can design and develop 

new special products to suit individual applications. 

Whatever the application all products will meet 

Lindapters own exacting standards ensuring that 

they are safe, quick and easy to install saving the 

customer both time and money by reducing 

installed costs. As the vast majority of Lindapter 

products require no site drilling or welding steel 

sections can, if and when necessary, be reused 

ensuring both current and future environmental and 

sustainability issues can be met.

Sample Project 

Seedhill Bridge, Lancashire, England 

Bridge refurbishment: 

Due to the age and condition of the structure the use of welded shear 

studs was not possible. Instead modified Hollo-Bolts ® were used which 

enabled the bridge deck refurbishment to be completed on time and to 

specification.

Girder Clamps Steelwork Fixings 1 

Components of a Girder Clamp 

1. Standard Grade 8 Hex Nut 

2. Standard Hardened Washer 

3. Lindapter Clamp 

Dependent on the application different clamps could be used i.e. 

Types A, B, BR, AF, LR, LS, D2 or D3. 

4. Packing Piece 

In combination with the clamps mentioned above these parts 

increase the tail length to enable the product to sit correctly on the 

beam. 

5. Location Plate (can be supplied if required) 

This is an essential part of the girder clamp assembly that enables 

all the components to be located in the correct position. The hole 

centres and plate thickness are calculated to suit the individual 

application. 

6. Lindapter Clamp 

This can be of a similar type as 3 (above), although certain products 

are designed to specifically work together i.e. A + B.

bolt head captive. The skirt prevents the clamp rotating during 

installation. For flanges up to 5°. For thicker flanges packings P1 long 

and P2 long are available. For correct tail length/packing combinations 

please see page 23. 



Correct Installation: Setscrew S needs to be adjusted so that V is 

1mm shorter than the flange thickness prior to installation. Adjust the 

setscrew after installation so that the bolt Z is 90° to the clamp and the 

clamp contacts the flange with area ‘K’ only.

Loads and Specifications Steelwork Fixings 1 

Loads and Specifications 

Reference is made throughout this catalogue to loads related to our product applications. Given loads are for boltgrade 8.8 unless otherwise stated. 

These are defined below. Should you have any difficulty in selecting the correct product for your needs, please contact us. 

Tensile Loading 

In tensile applications the load 

transmits a force parallel to the 

centre line of the bolt shank, 

hence applying a load to the 

contact point of the Lindapter. 

See product data tables for 

allowable tensile loads at varying 

bolt sizes. 

Combined Loads 

When the fixings are subject to 

more than one load condition, 

the resulting forces must be 

calculated to determine the 

product and bolt sizes required. 

Please contact Lindapter with 

your application. 

Frictional Loading 

The force is applied at 90° to 

the bolt shank. The point at 

which slip occurs depends 

upon the condition and finish 

of the steelwork, the coating 

of the Lindapter and the 

grade of bolt used. Slip is 

defined as the constant load 

at which relative movement 

between clamped 

components exceeds 

0.1mm. 

Compression Loading 

Force here is applied direct to 

the supporting section rather 

than the Lindapter products. 

If, however, there is a gap 

between the surfaces being 

connected, the buckling 

strength of the supporting 

fabrication must be considered. 

Shear Loading 

The Safe Working Load of the 

assembly is determined by the 

bolt grade and diameter as the 

force is resisted by the cross 

sectional area of the bolt 

shanks. It is recommended that 

reference be made to the bolt 

manufacturers’ technical 

literature or the relevant 

structural steel design code to 

ascertain a Safe Working Load 

per bolt. 

Torque 

The recommended torque 

values stated in the product 

sections must be applied in 

order to achieve the stated Safe 

Working Loads. Any reduction in 

torques applied will lower the 

product Safe Working Load and 

is not recommended.

Cavity Fixings 2 

Cavity Fixings 

In the late 1940’s Lindapter revolutionised the 

concept of ‘blind’ fixing, or where limited access is 

available, with the development of the Lindibolt. 

Some time later, following the introduction and 

wide acceptance of hollow section steelwork, the 

range was expanded to include the Hollo-Bolt ® 

. 

Due to the continued development and expansion 

of SHS into the wide variety which is available 

today from square, rectangular, circular to oval this 

product group has also seen a rapid expansion in 

diameters, lengths, finishes, and head types finally 

culminating in the Design Councils Millennium 

Products Award for Innovation which the 

Hollo-Bolt ® attained in 2000. 

Following comprehensive testing the Hollo-Bolt ® is 

now included in the BCSA/SCI publication ‘Joints 

in Steel Construction – Simple Connections’, more 

commonly known simply as the Green Book, as 

well as being approved by the Deutsches Institut 

für Bautechnik. 

The Hollo-Bolt ® is ideal for use on any steel 

structure eliminating the need for unsightly welding 

or strapping, installation is simple and quick 

requiring only the type of hand tools commonly 

available on site. 

Typical Hollo-Bolt ® applications include: 

• Primary Steelwork 

• Secondary Steelwork 

• Bridges 

• Cladding 

• Balconies 

• Towers and masts 

• Staircases and handrails

1) The thickness of the outer ply needs to be at least 8mm. If necessary spacer washers should be used beneath the collar to 

increase the thickness to 8mm. 

2) The Hollo-Bolt ® can be used on a wide variety of SHS sections; those shown above are only representative to give an 

indication of variations in Hollo-Bolt ® 

capacity. 

The safe working loads, in both tension and shear, are applicable to the Hollo-Bolt ® 

only, failure of the section, particularly 

on those with thin walls and a wide chord face, could occur at a lower figure and its strength should be checked using the 

‘Green Book’ design guide.

Composite Decking Fixings 3 

Composite Decking Fixings 

Lindapter composite decking fixings have all been 

designed in conjunction with the various decking 

manufacturers to ensure they fulfil the necessary 

requirements from ease of installation to carrying 

capacity. All the fixings are designed to fit inside 

the dovetail shaped re-entrant channel which is 

common throughout all the profiles and give a 

secure point from which building services can be 

suspended with guaranteed capacities. 

To guarantee the published capacities it is 

important that all the Lindapter Composite Decking 

Fixings are installed only when the slab has been 

poured and the concrete reaches full strength. 

Advantages include: 

• Speed of installation 

• No special tools required 

• No weakening of the decking profiles 

• No damage of the surfaces of the decking 

• No possibility of delamination 

• Adjustable and easily removable

Floor Fixings 5 

Floor Fixings 

When designing the floor fixing range of products for chequer plate 

and both square and rectangular open bar grating Lindapter combined 

speed with ease of installation. None of the products require any site 

drilling and/or welding to be done and can easily be installed from 

above the flooring; this means no requirement for scaffold towers, 

access platforms or MEWP hire giving easier compliance with the 

onerous work at height regulations. 

Both the Floorfast ® & Grate-Fast ® are covered by Lloyds Register Type 

Approval in respect of their clamping force and resistance to loosening 

in areas subject to shock and vibration. Without a need for the issuing 

of hot work permits, they are particularly suited to applications where 

safety is of paramount importance such as in offshore and onshore 

petrochemical and processing industries although they are equally 

ideal for applications in all other industrial environments.
