M4 Metric Stainless Allen Socket Head Bolt, Low Profile

A2-50 Stainless / Low Head Height

Low Profile socket head bolts are designed to be used in tight work areas where a reduced head height is required. An allen wrench is used to install these screws, allowing access into spaces 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.

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.


A2-50 Stainless Steel is commonly used in damp environments for corrosion resistance, popular across a wide range of industries: automotive, agriculture, food processing, clean energy, etc.

For any application involving marine (salt water), use A4 / 316 Stainless Steel material, available as special order.

Also known as low head or thin head socket cap screw or hexagon socket head cap screw. Reduced height cylindrical head screw meant to be used with an allen wrench.
