Value Collection R64406634 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R64406634 is a 1/4-20 UNC hex socket cap screw designed for secure fastening in mechanical, structural, and equipment assembly applications. The screw features a 3/4-inch length under head and accepts a 3/16-inch hex drive key for installation. Constructed from 18-8 stainless steel with a bright, uncoated finish, it offers solid corrosion resistance in environments where mild chemical exposure or moisture is a factor. This fastener is suited for use by maintenance technicians, millwrights, HVAC installers, and general trade professionals who need a reliable, standard-thread cap screw in a corrosion-resistant alloy.

This hex socket cap screw is commonly used in light-duty to medium-duty mechanical assemblies, equipment panels, brackets, and enclosures. Its 1/4-20 UNC thread pattern is one of the most widely used coarse-thread standards in North American trade work, making it a common choice for field repairs, OEM replacement, and general fabrication tasks across HVAC, plumbing, electrical, and industrial service environments.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 3/4-inch length under head suits typical bracket and panel fastening depths
• 3/16-inch hex socket drive for use with standard hex keys or Allen-style bits
• 18-8 stainless steel construction provides corrosion and oxidation resistance
• Bright, uncoated finish — no plating to crack, chip, or introduce galvanic concerns with stainless hardware

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring an 18-8 stainless fastener with a 3/4-inch under-head length and 3/16-inch hex drive.

Installation Notes

Install using a 3/16-inch hex key or appropriately sized Allen bit driver. Ensure the mating tapped hole or nut is clean and free of debris before threading. When fastening into dissimilar metals, consider the potential for galvanic interaction and use appropriate isolation hardware if needed. Do not overtighten stainless steel fasteners into tapped aluminum or soft alloy holes, as galling can occur — apply an appropriate anti-seize compound where recommended by the equipment manufacturer.
