Description
High Tensile Allen Cap Screw — Grade 10.9 hex socket (allen) for machinery, tooling, dies and high-strength assembly. Stocked across common sizes and lengths.
The high-tensile Allen cap screw (socket head cap screw) is a high-strength bolt with a cylindrical head and an internal hexagon (Allen) drive, tightened with a hex key. Its high-tensile alloy construction and compact head make it the standard fastener for machinery, tooling, dies and precision assemblies where strength and a clean, recessed head are needed. The socket drive allows high torque in tight spaces where a spanner could not reach.
High-tensile Allen cap screws are supplied in a range of diameters and lengths, typically to Grade 12.9 or equivalent high-strength ratings. Their strength and socket drive suit machine building and demanding mechanical assembly. Confirm the sizes and grade in the specifications below.
