Value Collection 354-0532-01 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 354-0532-01 is a flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies and structural connections. Sized at 5/16-18 x 2 inches overall length with a partially threaded shank, it features an 82-degree flat head and a Torx Plus T40 drive for high-torque installation with reduced cam-out. Manufactured from alloy steel with a black oxide finish, the screw delivers solid tensile strength and moderate corrosion resistance in controlled environments. Licensed tradespeople and maintenance technicians working on fabricated components, equipment frames, and fixtures install this fastener class regularly.

This screw suits residential and commercial maintenance, equipment manufacturing, and industrial assembly where a low-profile countersunk head is required. The 5/16-18 UNC thread designation makes it compatible with standard inch-system tapped holes and threaded inserts across a wide range of substrates. The black oxide finish blends into dark or painted metal surfaces and provides a base layer of corrosion resistance for indoor and light-duty applications. Typical installation scenarios include panel mounting, machinery guards, and structural steel subassemblies.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• Torx Plus T40 drive reduces cam-out under high installation torque
• Partially threaded shank provides clamping force across joined materials
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers moderate corrosion resistance for indoor use
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard 5/16-18 UNC tapped holes and countersunk applications following inch-system fastener specifications per ASME/ANSI B18.3.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional using a calibrated T40 Torx Plus bit. Ensure the mating hole is tapped to 5/16-18 UNC and countersunk to 82 degrees before driving the fastener. De-energize and lock out any equipment before accessing fastener locations on live machinery. Do not substitute a standard Torx bit for the Torx Plus drive, as this may damage the drive recess.
