Value Collection R57001109 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R57001109 is a fully threaded hex head cap screw designed for general fastening applications across mechanical, plumbing, electrical, and HVAC trade work. Sized at 1/4-20 x 5 inches, it features a Unified National Coarse (UNC) thread form and is manufactured from 18-8 stainless steel with a bright, uncoated finish. The full-thread design provides maximum engagement along the entire length under the head, making it well suited for through-bolting applications where grip length flexibility is needed. Licensed tradespeople and maintenance professionals working with corrosion-resistant fastener requirements will find this screw a reliable choice for both indoor and outdoor service environments.

This hex head cap screw is appropriate for residential and light commercial applications where 1/4-20 UNC fasteners are specified. Typical uses include equipment mounting, panel assembly, pipe hanger hardware, and structural bracketing in corrosive or moisture-prone environments. The 18-8 stainless steel construction makes it a common selection for coastal installations, mechanical rooms, pool equipment enclosures, and any setting where carbon steel fasteners would be prone to rust or galvanic issues. It is sold individually with a minimum order quantity of 5 units.

Key Features

• 18-8 stainless steel construction provides strong corrosion resistance in wet and humid environments
• Fully threaded along the entire 5-inch length under head for maximum thread engagement
• 1/4-20 UNC thread standard ensures broad compatibility with standard nuts and tapped holes
• Bright uncoated finish — no coating to flake, chip, or interfere with electrical or mechanical clearances
• Hex drive head works with standard hex keys, wrenches, and socket sets common on trade job sites

Compatibility

Designed as a standard 1/4-20 UNC fully threaded hex head cap screw for use with any mating 1/4-20 nut or tapped component following Unified National Coarse thread specifications.

Installation Notes

Install using the appropriate 7/16-inch hex wrench or socket. Ensure mating threads are clean and free of debris before driving the fastener. When installing into tapped aluminum or soft metal, avoid over-torquing, as stainless fasteners can gall — apply an anti-seize compound if thread galling is a concern. Always follow applicable mechanical codes and equipment manufacturer torque guidelines where specified.
