Value Collection R40694438 Hex Socket Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R40694438 is a hex socket cap screw designed for secure, high-strength fastening in applications where a low-profile head and internal hex drive are required. Threaded to the 1/4-28 UNF fine-thread standard, this screw features a 3/4-inch length under head and accepts a 3/16-inch hex key for installation. It is manufactured from 18-8 stainless steel, providing corrosion resistance suitable for both indoor and outdoor environments. This fastener is commonly installed by mechanical contractors, pipefitters, and maintenance technicians working on equipment assemblies, HVAC hardware, plumbing brackets, and general industrial fixtures.

This screw is appropriate for use in residential and light commercial mechanical installations where fine-thread engagement, corrosion resistance, and consistent torque retention are required. The 1/4-28 UNF thread pitch is well-suited to applications involving thinner materials or where vibration resistance benefits from finer thread engagement. Typical install scenarios include equipment panel fastening, bracket assembly, and component mounting on metal frames. Sold individually but subject to a minimum order quantity of 100 units per order.

Key Features

• 1/4-28 UNF fine-thread specification for reliable engagement in metal assemblies
• 3/4-inch length under head suits standard bracket and panel thickness applications
• 3/16-inch internal hex drive for use with standard Allen or hex key sets
• 18-8 stainless steel construction resists rust and corrosion in wet or outdoor environments
• Low-profile socket cap head design for installations with limited clearance

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 1/4-28 UNF hex socket cap screw with a 3/4-inch length under head.

Installation Notes

Installation is performed using a 3/16-inch hex key or Allen driver. Ensure the mating threaded hole or nut is clean and free of debris before threading the screw. Power down or de-energize any equipment before servicing fastened assemblies. Do not overtighten stainless steel fasteners, as galling can occur; apply an anti-seize compound when installing into stainless or aluminum threaded holes.
