Value Collection 63518 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 63518 is a hex socket cap screw designed for secure fastening in applications where a clean, recessed drive is required. The screw features a 1/4-20 UNC thread size and a 3/4-inch length under head, accepting a 3/16-inch hex key drive. Manufactured from 316 stainless steel, this fastener offers strong corrosion resistance in wet, marine, and chemical-exposure environments. It is suited for mechanical assemblies, equipment maintenance, and fabrication work performed by HVAC technicians, plumbers, electricians, and general tradespeople.

This hex socket cap screw is a practical choice for residential and commercial maintenance applications requiring a low-profile head and flush or recessed installation. The 1/4-20 UNC thread is a widely used standard, making this fastener compatible with a broad range of tapped holes and threaded inserts in equipment enclosures, brackets, and structural components. Minimum order quantity is 50 pieces, making it appropriate for stocking in a service vehicle or shop inventory.

Key Features

• 316 stainless steel construction provides superior corrosion and oxidation resistance
• 1/4-20 UNC thread is a common standard for trade and industrial fastening applications
• 3/4-inch length under head suits shallow to medium-depth fastening needs
• 3/16-inch hex socket drive allows torque application with a standard hex key or Allen driver
• Recessed socket head keeps the fastener profile low and reduces snag risk in tight assemblies

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any tapped hole or threaded insert accepting 1/4-20 thread pitch.

Installation Notes

Install using a 3/16-inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Avoid cross-threading by starting the fastener by hand. When used in equipment with live electrical or pressurized systems, de-energize or depressurize the system fully before disassembly or fastener replacement.
