Value Collection R56000786 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R56000786 is a hex socket cap screw designed for secure, high-torque fastening in applications where a standard hex head is not practical. The 1/4-20 UNC thread provides a coarse pitch suitable for general fastener engagement in metal, plastic, and composite assemblies. Manufactured from 316 stainless steel, this screw resists corrosion and pitting in wet, marine, and chemical environments. The 5/16-inch internal hex drive accepts a standard hex key or Allen driver. With a 2.5-inch length under head, this fastener is suited for medium-depth through-bolt and tapped-hole installations. Trades commonly used in HVAC equipment assembly, plumbing, and general mechanical work will recognize this as a standard socket cap profile.

This fastener is used in residential and commercial maintenance and fabrication work wherever a recessed drive and flush or sub-flush head seating is required. Common applications include equipment panel attachment, bracket mounting, and component assembly in corrosive or high-moisture environments. The 316 stainless steel grade makes it appropriate for outdoor, coastal, marine, and chemical-exposure service conditions where lower-grade fasteners would corrode prematurely.

Key Features

• 1/4-20 UNC coarse thread for reliable engagement in standard tapped holes
• 2.5-inch length under head accommodates medium-depth fastening applications
• 5/16-inch hex socket drive for use with standard Allen keys or hex drivers
• 316 stainless steel construction provides superior corrosion resistance in marine and wet environments
• Socket cap head profile allows installation in recessed or tight-clearance locations

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring a 1/4-20 threaded fastener with a socket cap head profile.

Installation Notes

Installation should be performed with a correctly sized 5/16-inch hex key or Allen driver to avoid rounding the drive socket. Verify that the mating tapped hole or nut is also 1/4-20 UNC thread before installation. Do not exceed the recommended seating torque for 1/4-20 stainless fasteners, as 316 stainless is susceptible to galling if over-driven without anti-seize compound. Power down or de-energize any equipment being serviced before installing or removing fasteners from live assemblies.
