8mm (5/16") standard hexagon washer head fastener.
Fasteners in this range are all fully threaded. See fastener specifications link below,
These fasteners have a minimum 500hr SST coating. Link below.
Use a washer to seal head of fastener (make watertight) as an isolator, or to increase pullover value. A washer must be fitted if a colour cap is to be used. A washer is also a good indicator of over/under driving which can cause failure.
When fixing through two or more steel sheets, with gaps/spaces, remember to predrill upper layers to prevent jacking problems.
Use a purpose made screwgun for installation. Cordless drivers and drill drivers are ideal with torque set fairly high on a high speed and in driver mode. Please note: Impact drivers should not be used under any circumstance and automatically voids any warranties.
Figures throughout will be ultimate test results with no safety factors.
Typical applications include fixing frame ties and wall ties to heavy steel beams and columns.
