1/4-20 x 1 3/4 Alloy Steel Low Head Socket Cap Screw is commonly used when covers, guards, or tooling plates need a lower head than a conventional socket cap screw. The internal wrenching design is practical for tight equipment layouts where external wrench clearance is limited.

The fastener is appropriate for brackets, panels, and access covers, where the bearing surface and reduced profile can help keep exposed fasteners controlled. It remains useful in brackets, panels, and access covers, where the bearing surface and reduced profile can help keep exposed fasteners controlled. Internal hex drive engagement keeps the wrenching feature within the head, supporting compact installation and service access.

For replacement sourcing, the thread size and length identify the fastener while the low-head dimensions confirm fit in the existing counterbore, cover, or guarded area.
