Nails & Screws
NOT ALL FIXINGS ARE THE SAME...
James Robinson, Sales and Marketing Director at Samac Fixings, explains why the
importance of quality fixings cannot be overstated and why understanding that not all
screws are the same is so important.
As the industry evolves with new building
regulations and technological
advancements, the demand for
specialised, high quality fixings has never been
higher. The design and coatings of screws, from
wood screws through to heavy duty structural
fixings, cater for a wide range of applications
and have the potential to save significant time
and money for contractors. It is true to say that
today’s modern fixings are way more than “just
a screw” and are surely one of the unsung heroes
out of all the construction materials.
The construction industry is continuously
adapting to new challenges, including increased
levels of insulation required by evolving building
regulations. Part L of the UK building regulations
now mandates a minimum roof insulation level of
0.18 W/mK for all new-build homes and
extensions. This significant update necessitates
the use of thicker insulation materials to meet the
new standard, thereby creating a need for longer
screws in the construction process.
Understanding this industry shift, Samac Fixings
has responded proactively by adding 6 x 220mm
and 6 x 240mm screw lengths to its Performance
Range. These new sizes are meticulously
engineered to travel through the increased
thickness of the latest insulation materials,
ensuring compliance with the updated
regulations, while maintaining Samac's hallmark
of quality and reliability.
Adhering to building regulations is not just a legal
necessity; it’s also a matter of safety and
efficiency. The longer screws in the Performance
Range specifically address the requirements of
Part L, ensuring that contractors are not only
compliant but also confident in the integrity of
their work. Moreover, these longer screws
distribute pressure more evenly
across the insulation layer. This
feature is critical for maintaining
the stability of the insulation
over time, ensuring that buildings remain energy
efficient and compliant with the latest standards.
Coatings
One of the key aspects of Samac’s Performance
Range is the Ruspert coating. This coating is not
just about aesthetics; it provides enhanced
corrosion resistance, making the screws suitable
for a variety of environments, including external
applications. The durability offered by this coating
extends the life of the fixings, thereby reducing
the need for frequent replacements and saving
costs in the long term.
The design of a screw also plays a pivotal role in
its efficiency. Certain screws are engineered for
specific applications. Take, for instance, TEK
Screws which are designed with a self-drilling
capability that eliminates the need for predrilling,
saving you time and money. This feature
also ensures a secure and tight fit, reducing the
risk of leaks and other issues that can arise from
poorly secured sheet metal.
Collated nails, such as the Viper range for roofing
applications offer another example. Designed with
precision, these nails ensure a strong hold and
easy application, crucial for the fast-paced
nature of first fix roofing. Likewise, the Atlas
Bolts, known for their strength and reliability,
are perfect for heavy-duty applications where
security and durability are paramount.
Furthermore, the longevity and reliability of
these fixings mean fewer callbacks for repairs,
a significant saving for contractors.
However, understanding when to use
the correct screw for a specific
application in the construction
industry is not just a matter of
efficiency; it’s a crucial aspect of
safety, cost management and overall project
success. The importance of this knowledge
cannot be understated, as the use of
inappropriate fasteners can lead to dangerous
outcomes and be a source of significant waste.
For example, a screw not designed for loadbearing
purposes used in structural applications
may fail under stress, leading to structural
integrity issues or even catastrophic collapses.
Similarly, screws that are not corrosion-resistant,
if used in outdoor or moisture-prone
environments, can corrode and weaken over
time, posing a risk to the stability of the
structure.
So, not all screws are the same – and the saying
“you get what you pay for” holds particularly true
in the world of construction fixings. The benefits
of investing in quality extend beyond the
immediate project. They ensure compliance,
enhance safety, save time and money in the long
run, and contribute to the overall success and
reputation of a construction business.
