Request Information

1/4-20 x 2 Alloy Steel Low Head Socket Cap Screw is specified when machine design requires internal-hex fastening with a reduced head height. Its alloy steel construction and internal hex drive support compact mechanical fastening without requiring an external wrenching surface.

Common use cases include guarding and machine covers, where the reduced head height helps preserve clearance around moving parts and service panels. It can also support robotics and automation systems, where compact socket screws help designers work inside tight machine envelopes. The verified head diameter, head height, and hex key size below help purchasing teams confirm fit before quoting or ordering.

Because low-head dimensions are controlled by nominal screw diameter rather than length, this fastener should be selected by thread, length, and the available clearance above the assembly.
