Detail & Specs
Class 12.9 Extreme Strength / Full Head Height
Socket head bolts are great for limited space installation areas. An allen wrench is used to install these screws, allowing access into tight locations where a traditional external hex drive bolt would not fit.
A black oxide finish provides minimal corrosion resistance, best for indoor, dry environments. This finish is not suitable for outdoor applications, and will rust when exposed to moisture..
Partially threaded socket cap bolts have an unthreaded length under the head that is stronger than the threaded portion of the bolt. The unthreaded / threaded length dimensions vary by diameter. Fully threaded socket cap screws are meant to engage the entire length with a tapped hole.
These bolts can be used with many different styles of locking and non-locking nuts, tightly clamping together whatever the cap screw is being used to secure.
Also known as finely threaded allen cap screw, hex drive screw, socket head bolt, hexagon socket head cap screw. Cylindrical head screw meant to be used with an allen wrench.
