Value Collection 721319BR Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 721319BR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Manufactured from alloy steel with a black oxide finish, this screw delivers solid mechanical strength alongside modest corrosion resistance in controlled environments. It features an 82-degree flat head and a 5/8-inch hex socket drive, making it compatible with standard hex keys and Allen wrenches. The 1-8 thread size follows UNC (Unified National Coarse) standards, and the fastener is fully threaded along its 2-3/4-inch overall length. It meets ASME/ANSI B18.3 and ASTM F835 standards. Machinists, maintenance technicians, and mechanical contractors install this type of fastener where a low-profile, recessed head is required.

This flat socket cap screw is suited for general industrial and mechanical assembly work where a countersunk socket drive fastener is specified. The fully threaded body provides consistent thread engagement across the full grip length, making it a practical choice for through-hole applications in steel, aluminum, and similar materials. The black oxide finish offers a uniform appearance and mild surface protection. This screw is sold individually and is appropriate for low-volume repair, replacement, or prototype work where single-unit quantities are needed.

Key Features

• 82-degree flat head profile for flush or countersunk seating
• 5/8-inch hex socket drive compatible with standard Allen keys and hex wrenches
• Fully threaded 2-3/4-inch overall length for maximum thread engagement
• Alloy steel construction for reliable mechanical strength
• Black oxide finish provides uniform appearance and mild surface protection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC flat socket cap screw for use in countersunk holes in general industrial, mechanical, and maintenance assembly applications where a 1-8 thread and 2-3/4-inch overall length are specified.

Installation Notes

Install using a 5/8-inch hex key or Allen wrench; ensure the mating countersink is machined to 82 degrees for proper head seating. Verify thread engagement depth and hole condition before driving to avoid cross-threading. Do not exceed the torque rating of the mating material. Fastener installation in structural or pressure-bearing assemblies should follow applicable engineering specifications and relevant industry standards.
