Wrenches Technical Information<br />
Combination Wrenches<br />
<strong>Britool</strong> combination wrenches feature Stress Rel<strong>ie</strong>f Drive on the ring end.<br />
All open jaw ends feature a constant radius of curvature – reducing stress<br />
concentrations and jaw flexing. Both of these features enhance fastener grip<br />
and prolong both tool and fastener life. All <strong>Britool</strong> combination wrenches are<br />
manufactured to ISO 7738.<br />
<strong>Britool</strong> combination wrenches are suppl<strong>ie</strong>d in four different length variants<br />
– short, standard, long and extra long.<br />
<strong>Britool</strong> combination wrenches are clearly marked with the wrench size on the<br />
open jaw head for ease of identification.<br />
Open Jaw Wrenches<br />
All open jaw ends feature a constant radius of curvature – reducing stress<br />
concentrations and flexing of the jaws.<br />
Ring Wrenches<br />
<strong>Britool</strong> Ring Wrenches are offset at 45˚ for ease of access and feature Stress<br />
Rel<strong>ie</strong>f Drive.<br />

<strong>Britool</strong> wrenches are manufactured to the latest ISO standards. All are forged<br />
from the highest quality steel and precision machined to exacting standards.<br />
They fulfil the needs of the professional engineer.<br />
• Drop forged to ensure uniform grain structure, giving increased strength<br />
and reliability<br />
• Heat treated in carefully controlled conditions to ensure optimum<br />
performance for every wrench<br />
• Chrome plated for maximum corrosion protection<br />
<strong>Britool</strong>’s advanced Stress Rel<strong>ie</strong>f Drive (SRD) is standard on all 12 point rings.<br />
This reduces fastener wear, assists in the removal of worn fasteners, and enables<br />
higher torque loads to be appl<strong>ie</strong>d.<br />
<strong>Britool</strong>’s advanced ring configuration increases the contact area between the<br />
socket and the fastener, minimising stress and reducing the chance of fastener<br />
damage.<br />
Because the load is appl<strong>ie</strong>d to the flat of the fastener, rather than the corners<br />
– even if the fastener is already damaged – the drive is superior to a standard<br />
profile socket.<br />
