Value Collection 354-5816-01 Flat Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 354-5816-01 is an 8-32 x 1 inch flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. Manufactured from alloy steel with a black oxide finish, it provides moderate corrosion resistance and reduced light reflection. The 82-degree flat head seats flush with the workpiece surface when installed in a properly prepared countersink. Drive engagement is via a Torx Plus T20 socket, which delivers higher torque transfer and reduced driver cam-out compared to standard hex socket drives. The screw is fully threaded over its 1 inch overall length using UNC thread form at 8-32.

This screw is suited for light-to-medium duty mechanical assemblies, panels, enclosures, and brackets where a flush surface finish is required after fastening. The black oxide finish makes it appropriate for applications where minimal glare or a darkened appearance is preferred, such as interior equipment housings or control panel assemblies. It meets ASME/ANSI B18.3 and ASTM F835 standards, making it appropriate for applications with dimensional and mechanical property requirements governed by those specifications. Sold individually; minimum order quantity is 100 pieces.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• Torx Plus T20 drive reduces cam-out and allows higher installation torque than hex socket
• Fully threaded 8-32 UNC over entire 1 inch overall length
• Alloy steel construction with black oxide finish for moderate corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 8-32 UNC flat socket cap screw replacement or new installation fastener for any application accepting an 82-degree countersunk Torx Plus T20 drive screw in that thread size and length.

Installation Notes

Install using a T20 Torx Plus bit or driver. The mating countersink must be machined to 82 degrees for proper flush seating. Verify countersink diameter matches the screw head diameter before assembly to avoid head stand-off or pullthrough. Follow applicable torque specifications from your engineering design documentation or the relevant ASME standard for the material and joint being fastened.
