Value Collection -36818-2 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION -36818-2 is a 1/4-20 x 2.5-inch flat socket cap screw made from alloy steel with a black oxide finish. It features an 82-degree flat head and a 5/32-inch hex socket drive. The screw is partially threaded and conforms to UNC thread standards. It meets ASME/ANSI B18.3 and ASTM F835 fastener standards. This type of fastener is installed by machinists, maintenance technicians, and tradespeople requiring a low-profile, countersunk fastening solution in ferrous metal assemblies.

This flat socket cap screw is suited for applications where the fastener head must sit flush or below the mating surface. Common use cases include mechanical assemblies, jigs and fixtures, enclosure panels, and equipment frames in industrial and commercial settings. The black oxide finish provides mild corrosion resistance and reduces light reflection. The alloy steel construction provides strength appropriate for medium-to-high-load fastening applications. Sold in a package quantity of 25.

Key Features

• 82-degree flat head profile allows flush or countersunk installation
• 5/32-inch hex socket drive for standard Allen key or hex bit installation
• Partially threaded shank — 1/4-20 UNC thread form
• Alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and low reflectivity
• Meets ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed as an OEM-style replacement or general-use flat socket cap screw for standard 1/4-20 UNC countersunk threaded applications in ferrous metal components.

Installation Notes

Installation is performed using a 5/32-inch hex key or compatible hex drive bit. Ensure the mating hole is properly countersunk to the correct 82-degree angle before installation. Disengage all power and relieve any mechanical load from the assembly before replacing fasteners in live equipment. Do not exceed the fastener's rated tensile strength by overtightening.
