Value Collection 63520 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 63520 is a hex socket cap screw designed for secure fastening in applications where a low-profile, high-strength connection is required. Sized at 1/4-20 UNC thread with a 1-1/4 inch length under head, it accepts a 3/16 inch hex drive for installation with a standard Allen key or hex bit. Manufactured from 316 stainless steel, this fastener offers strong corrosion resistance, making it suitable for wet, chemical, or marine-adjacent environments. It is a standard choice for mechanical assemblies, equipment mounting, and structural connections across trade and industrial settings.

This cap screw is used across a broad range of trade and industrial applications including HVAC equipment assembly, plumbing fixture mounting, electrical enclosure hardware, and general mechanical fabrication. The 1/4-20 UNC thread is one of the most common unified coarse thread standards, making this fastener compatible with a wide variety of tapped holes and threaded inserts in both field and shop work. The 316 stainless steel construction is particularly well suited for outdoor, coastal, or high-moisture environments where carbon steel would corrode.

Key Features

• 1/4-20 UNC thread — one of the most widely used unified coarse thread sizes in trade applications
• 1-1/4 inch length under head for sufficient thread engagement in standard assemblies
• 3/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 316 stainless steel construction provides strong resistance to corrosion and oxidation
• Low-profile socket cap head design for use in confined or flush-mount installations

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any tapped hole or threaded insert matching the 1/4-20 unified coarse thread specification.

Installation Notes

Install using a 3/16 inch hex key or hex bit driver; do not use an undersized driver as it will damage the socket. Ensure the mating thread is clean and free of debris before installation. Fasteners should be torqued per the assembly specification for the equipment being serviced. In structural or pressure-bearing applications, follow applicable mechanical codes and manufacturer guidelines.
