Value Collection 721411BR Flat Socket Cap Screw 3/4-16

Product Description

The VALUE COLLECTION 721411BR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Sized at 3/4-16 UNF by 1-3/4 inches overall length and fully threaded, it is driven with a 1/2-inch hex socket tool. The 82-degree flat head allows the fastener to seat flush with or below the mating surface. Constructed from alloy steel with a black oxide finish, this screw delivers solid mechanical strength and moderate corrosion resistance in typical industrial, mechanical, and equipment assembly environments. Machinists, millwrights, and maintenance technicians commonly install this type of fastener.

This flat socket cap screw is suited for machine assembly, tooling fixtures, equipment frames, and structural joints where a low-profile head is required to avoid interference with mating components or moving parts. The UNF thread series and alloy steel construction make it appropriate for high-load, close-tolerance applications common in manufacturing and industrial maintenance. Sold individually, it fits standard countersunk hole patterns per ASME/ANSI B18.3 specifications.

Key Features

• 82-degree flat head seats flush in countersunk holes to eliminate surface protrusion
• 1/2-inch hex socket drive for secure torque transfer with standard Allen or hex key tools
• Fully threaded 3/4-16 UNF shank for maximum thread engagement over the full 1-3/4-inch length
• Alloy steel construction provides high tensile and shear strength for demanding applications
• Black oxide finish offers mild corrosion resistance and reduces light reflection on exposed hardware
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard countersunk hole applications machined to ASME/ANSI B18.3 specifications for 3/4-16 UNF flat socket cap screws with an 82-degree countersink angle.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a calibrated 1/2-inch hex key or socket driver. Ensure the mating countersink is machined to the correct 82-degree angle and proper depth before seating the screw. Power down or de-energize any equipment before performing fastener service on live machinery. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards for the material and joint configuration.
