Value Collection R64406621 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R64406621 is a hex socket cap screw designed for secure, high-torque fastening in mechanical, industrial, and trade applications. Featuring a 1/4-20 UNC thread with a 1 inch length under head, this fastener accepts a 3/16 inch hex drive for installation with a standard Allen key or hex bit driver. Constructed from 18-8 stainless steel with a bright uncoated finish, the R64406621 offers solid corrosion resistance and material strength suitable for both interior and exposed-environment assemblies. HVAC technicians, plumbers, electricians, and general contractors reach for fasteners like this when assembling equipment panels, mounting brackets, and equipment enclosures.

This screw suits a wide range of residential and light commercial applications where a compact, recessed-drive cap screw is required. The 1/4-20 UNC thread is one of the most common coarse-thread sizes in North American trade work, making this fastener a practical fit for equipment mounting, control panel assembly, pipe support hardware, and general structural fastening where stainless steel is specified for corrosion resistance or hygiene requirements.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 1 inch length under head for medium-depth fastening applications
• 3/16 inch hex socket drive for use with Allen keys or hex bit drivers
• 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• Bright uncoated finish maintains material properties without additional surface treatment

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for any tapped hole or nut meeting ANSI 1/4-20 coarse thread specifications.

Installation Notes

Install using a 3/16 inch hex key or hex bit driver; do not use an undersized driver, as it will round the socket. Torque to the specification required by the assembly or equipment manufacturer. When installing into tapped metal, ensure threads are clean and free of debris before driving. For stainless steel fasteners in stainless tapped holes, apply an appropriate anti-seize compound to prevent galling.
