Value Collection 36816 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 36816 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Sized at 1/4-20 x 1-1/4 inches overall length with full threading, it features an 82-degree flat head and a 5/32-inch hex socket drive. Manufactured from alloy steel with a black oxide finish, it delivers solid mechanical strength and moderate corrosion resistance in controlled environments. This fastener is fully threaded along its entire length, maximizing thread engagement in through-hole and tapped applications. Installation requires a standard hex key or Allen wrench. Sold individually with a minimum order quantity of 25 pieces.

This screw is suited for mechanical assemblies, machine components, and structural fixtures where a low-profile, flush-seating fastener is required. The 1/4-20 UNC thread pitch is one of the most common inch-series thread standards, making this fastener widely applicable across general industrial, manufacturing, and maintenance settings. The black oxide finish provides a clean appearance and mild corrosion resistance, making it appropriate for indoor and light-duty applications. Tradespeople and maintenance technicians working with inch-series hardware will find this a standard utility fastener.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 5/32-inch hex socket drive compatible with common Allen wrenches and hex keys
• Fully threaded 1/4-20 UNC for maximum thread engagement
• Alloy steel construction for mechanical strength
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 1/4-20 UNC fully threaded countersunk fastener per ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Install using a calibrated hex key or Allen wrench sized to 5/32 inch. Ensure the mating hole is countersunk to 82 degrees for proper head seating. De-energize and lock out any equipment before fastener replacement or assembly work. Do not exceed the rated mechanical load for the alloy steel grade in the given application.
