Value Collection 721413BR Flat Socket Cap Screw 3/4-16

Product Description

The VALUE COLLECTION 721413BR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 1/2-inch hex socket. Manufactured from alloy steel with a black oxide finish, this screw offers good mechanical strength and moderate corrosion resistance in protected environments. The 3/4-16 UNF thread is fully threaded along the 2-1/4-inch overall length, providing consistent thread engagement. It is installed by machinists, maintenance technicians, and assembly professionals working on mechanical assemblies, fixtures, and equipment.

This screw is suited for use in precision mechanical assemblies, tooling fixtures, machine frames, and structural components where a flush fastener surface is required. The UNF thread pitch is common in applications demanding finer thread engagement and greater tensile load capacity compared to coarse-thread equivalents. The black oxide finish reduces light reflection and provides mild corrosion resistance, making this fastener appropriate for indoor and controlled-environment installations.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• 1/2-inch hex socket drive for high torque input with standard Allen keys or hex bit drivers
• 3/4-16 UNF fully threaded at 2-1/4 inches overall length
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish for mild corrosion resistance and low-reflectivity surface
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard-dimension replacement or new-installation fastener for mechanical assemblies requiring a 3/4-16 UNF flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/2-inch hex key or socket driver. Countersink the mating hole to the appropriate 82-degree angle before installation to ensure proper head seating. Degrease threads and apply thread lubricant or threadlocker as required by the assembly specification. Do not exceed the torque rating specified by the assembly engineer or equipment manufacturer for this fastener size and grade.
