Value Collection 721415BR Flat Socket Cap Screw 3/4-16x3in

Product Description

The VALUE COLLECTION 721415BR is a flat socket cap screw designed for flush or countersunk fastening applications in structural and mechanical assemblies. Sized at 3/4-16 x 3 inches overall length, this fully threaded fastener features an 82-degree flat head profile and a 1/2-inch hex socket drive. Constructed from alloy steel with a black oxide finish, it delivers reliable clamping force while resisting light corrosion in interior environments. It conforms to ASME/ANSI B18.3 and ASTM F835 standards, making it suitable for precision-critical industrial, HVAC, and mechanical service work where dimensional consistency matters.

This fastener is suited for applications where a countersunk, low-profile head is required and the fastener must sit flush with or below the mating surface. Common installation scenarios include machine frames, equipment panels, and mechanical housings in residential and light commercial settings. The UNF thread standard makes it compatible with fine-thread tapped holes where vibration resistance or tight tolerance fits are required. Installers in HVAC, plumbing, electrical, and general mechanical trades will encounter this screw in panel and bracket assemblies.

Key Features

• 82-degree flat head profile for flush countersunk installation
• 1/2-inch hex socket drive for high-torque engagement with Allen or hex key tooling
• Fully threaded 3-inch alloy steel body for consistent clamping along the full fastener length
• Black oxide finish provides light corrosion resistance and reduced light reflection
• 3/4-16 UNF thread standard for fine-thread tapped hole compatibility
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw compatible with 3/4-16 UNF fine-thread tapped holes requiring an 82-degree countersunk flat head and hex socket drive.

Installation Notes

Installation requires a properly sized hex key or Allen driver matched to the 1/2-inch socket drive. The mating surface must be countersunk to 82 degrees to achieve full flush seating. Ensure the tapped hole thread specification matches 3/4-16 UNF before installation. De-energize or lock out any equipment before servicing fasteners on energized mechanical assemblies per applicable safety procedures.
