Hex Cap Screw · 1/4-20 x 1 in · Zinc-Plated Steel - Fasteners .250X1.00NCHC

What this product is for

This 1/4-20 x 1 in hex cap screw is used to fasten electrical brackets, supports, enclosures, channel accessories, and general hardware where a wrench-tightened hex head fastener is required.

Use for

Use for indoor electrical assemblies, panel hardware, strut accessories, equipment mounting, and general steel-to-steel fastening with a matching 1/4-20 nut or threaded hole.

Avoid for

Avoid for highly corrosive, washdown, or marine environments where stainless steel or a higher-corrosion-resistance finish is typically preferred. Avoid where exact grade, thread length, or certification is required unless confirmed before ordering.

Best for

Best for contractors and maintenance teams looking for a common imperial hex fastener size that fits standard 1/4-20 hardware and can be installed with standard hand tools.

Installed in

Typically installed in electrical rooms, commercial tenant fit-outs, service spaces, plant maintenance work, and general construction assemblies.

Why this product exists

It provides a standard hex head machine fastener for applications where slot, Phillips, or Robertson drives are not ideal and where wrench access gives better tightening control during assembly.

Compared with similar products

Compared with carriage bolts, this hex cap screw does not require a square hole. Compared with stainless fasteners, zinc-plated steel is typically more economical but offers lower corrosion resistance. Compared with fully unknown generic bolts, the key buying detail here is the common 1/4-20 x 1 in format used across electrical support hardware.
