Value Collection 204126C Hex Head Cap Screw 1/4-20 316 Ss

Product Description

The VALUE COLLECTION 204126C is a 1/4-20 hex head cap screw measuring 1-3/4 inches under the head, manufactured from Grade 316 stainless steel with a bright, uncoated finish. The fastener uses UNC thread standard and is partially threaded along its shank. Grade 316 stainless steel provides strong resistance to corrosion and chloride exposure, making this screw well suited for demanding environments. It is installed by mechanics, millwrights, plumbers, HVAC technicians, and other tradespeople who require a reliable, corrosion-resistant threaded fastener in structural or mechanical assemblies.

This screw is appropriate for use in residential, commercial, and light industrial applications where a corrosion-resistant imperial-thread fastener is required. Common installation scenarios include equipment mounting, pipe hangers, enclosure assembly, and mechanical hardware in wet or chemically exposed environments such as pool equipment rooms, marine-adjacent installations, and process piping systems. The 1/4-20 UNC thread pattern is a widely used inch-series standard compatible with standard hex nuts, lock nuts, and threaded inserts of the same specification.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chloride resistance
• 1/4-20 UNC thread standard for broad compatibility with inch-series hardware
• Partially threaded shank for reliable clamping force in through-bolt applications
• Bright, uncoated finish — no plating to chip, peel, or react with stainless mating hardware
• 1-3/4 inch length under head suits moderate-depth fastening applications

Compatibility

Designed for use with standard 1/4-20 UNC inch-series hex nuts, flat washers, lock washers, and threaded inserts. Suitable as a replacement or service fastener wherever a 1/4-20 x 1-3/4 inch Grade 316 stainless hex cap screw is specified.

Installation Notes

Install and tighten using a standard hex wrench or socket sized for a 1/4-20 hex head fastener. De-energize and lock out any equipment before fastening into live electrical enclosures or mechanical assemblies under load. Avoid mixing Grade 316 stainless fasteners with carbon steel hardware in wet environments to minimize galvanic corrosion risk. Torque to the value specified in the equipment manufacturer's documentation or applicable engineering standard.
