M8 Metric Allen Socket Head Bolt, Black Stainless Steel
A2-70 Stainless / 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.
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. The socket head may be smooth or knurled.
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.
