Value Collection 354-5808-01 Flat Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 354-5808-01 is an 8-32 x 1/2 inch flat socket cap screw designed for precision fastening applications where a flush or countersunk finish is required. Manufactured from alloy steel with a black oxide finish, this screw delivers solid corrosion resistance and a clean, low-profile seating surface. Drive interface is Torx Plus, size T20, which reduces cam-out and allows higher torque transfer than standard hex socket drives. The thread profile is UNC and the screw is fully threaded along its 1/2 inch overall length. It meets ASME/ANSI B18.3 and ASTM F835 standards, making it suitable for structural and mechanical assemblies where dimensional and strength compliance matter.

This fastener is a standard inch-series socket cap screw appropriate for light mechanical assemblies, electrical enclosures, machine guards, fixtures, and similar applications common in industrial, HVAC, electrical, and plumbing equipment manufacturing or field repair. The 82-degree flat head geometry seats flush in standard countersunk holes, which is especially useful where clearance is tight or a smooth mating surface is needed. Minimum order quantity is 100 pieces, sold in individual unit packaging per the supplier specification.

Key Features

• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish offers mild corrosion resistance and a low-glare appearance
• Torx Plus T20 drive reduces cam-out and supports higher installation torque compared to hex socket
• 82-degree flat head seats flush in standard countersunk holes
• Fully threaded 8-32 UNC shank along entire 1/2 inch length
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series UNC flat socket cap screw suitable for countersunk fastening applications in alloy steel or aluminum components requiring an 8-32 thread and 1/2 inch overall length.

Installation Notes

Install using a calibrated Torx Plus T20 driver or bit; do not substitute a standard Torx T20 bit as Torx Plus flanks have a different profile that affects engagement and torque transfer. Ensure the mating hole is properly countersunk to 82 degrees before installation. Verify thread condition and hole cleanliness before driving. Apply thread-locking compound if vibration is a concern in the service environment.
