Value Collection 721102PR Flat Socket Cap Screw 8-36

Product Description

The VALUE COLLECTION 721102PR is a flat socket cap screw designed for applications requiring a flush or countersunk head profile. It features an 82-degree flat head driven by a 3/32-inch hex socket and is fully threaded along its 5/8-inch overall length. The 8-36 UNF thread pitch makes it suitable for fine-thread fastening needs where vibration resistance and precise clamping force are priorities. Constructed from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance in covered or lightly protected environments. Machinists, maintenance technicians, and fabricators routinely install this type of fastener where a low-profile head is required.

This fastener is appropriate for use in precision assemblies, machine components, fixtures, and tooling where a flush-mount head is necessary to avoid interference with mating surfaces. The fine 8-36 UNF thread engages cleanly in tapped holes machined to ASME/ANSI B18.3 standards. It is suited to both light industrial and general mechanical assembly applications. Minimum order quantity is 100 pieces; package quantity is 1.

Key Features

• 82-degree flat head provides a flush, countersunk seating profile
• 3/32-inch hex socket drive for use with standard allen wrenches or hex-bit drivers
• Fully threaded 5/8-inch overall length, 8-36 UNF thread
• Alloy steel construction for high tensile strength
• Black oxide finish for a matte appearance and mild corrosion resistance
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw for use in tapped holes conforming to 8-36 UNF thread specifications per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 3/32-inch hex key or socket-bit driver. The mating countersink should be machined to an 82-degree included angle to achieve full head seating. Ensure the tapped hole is clean and free of debris before driving. Do not exceed the torque capacity of the alloy steel fastener by using impact drivers on fine-thread applications without appropriate controls.
