Brighton-best 401010 Hex Cap Screw 1/4-20 316 Ss Unc 100pk

Product Description

The BRIGHTON-BEST 401010 is a fully threaded hex cap screw in a 1/4-20 UNC thread pattern with a 1-inch length, supplied in a pack of 100. Manufactured from 316 stainless steel, this fastener delivers strong corrosion resistance in wet, chemical, and marine environments. The full-thread configuration provides maximum thread engagement across the full length of the shank, making it well suited for clamping applications where a nut is used or where the full grip depth is needed. Plumbers, HVAC technicians, and electricians reach for 316 stainless hardware when installations involve exposure to moisture, chlorides, or corrosive atmospheres.

These hex cap screws are commonly used in mechanical and utility installations where standard carbon steel fasteners would corrode prematurely. Typical applications include pipe hanger assemblies, equipment mounting in wet mechanical rooms, rooftop HVAC curb attachments, pool and spa equipment enclosures, and coastal or marine installations. The 100-piece pack is sized for job-lot stocking or service van inventory. The 1/4-20 UNC thread is one of the most common fastener sizes across trade work, fitting a wide range of standard nuts, inserts, and tapped holes.

Key Features

• 316 stainless steel construction for superior corrosion resistance in chloride and marine environments
• Full-thread (FT) design maximizes thread engagement for secure clamping with a nut
• 1/4-20 UNC thread - one of the most widely used coarse-thread fastener sizes in trade applications
• 1-inch length suitable for standard panel, bracket, and hanger installations
• Pack of 100 for job-lot stocking and bulk service use

Compatibility

Designed for use with standard 1/4-20 UNC nuts, flat washers, lock washers, and tapped components across HVAC, plumbing, electrical, and pool equipment installations.

Installation Notes

Installation requires a standard hex wrench or socket driver sized for a 1/4-inch hex cap screw head. When fastening into tapped holes or joining dissimilar metals in wet environments, verify galvanic compatibility to prevent accelerated corrosion. Do not exceed the rated torque range for 1/4-20 stainless fasteners, as 316 stainless can gall if over-tightened without anti-seize compound. Always follow applicable mechanical codes and equipment manufacturer torque guidance.
