Value Collection 581730BR Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION 581730BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features a 3/4-16 UNF thread — a fine-pitch unified thread that provides stronger thread engagement and better resistance to loosening under vibration compared to coarse-pitch alternatives. The screw measures 2-3/4 inches under the head and is driven with a 5/8 inch hex key. Constructed from alloy steel with a black oxide finish, this fastener delivers reliable tensile strength and moderate corrosion resistance in controlled environments. Machinists, millwrights, and industrial maintenance technicians are the typical installers for this fastener type.

This socket cap screw is suited for use in precision machinery, hydraulic assemblies, jigs and fixtures, and close-tolerance mechanical joints where a recessed drive and fine-thread engagement are required. The 3/4-16 UNF thread size accommodates applications demanding fine thread control, such as adjustable mounts, fluid-system fittings, and load-bearing structural connections. It is sold individually but must be ordered in multiples of 10 to meet the minimum order quantity requirement.

Key Features

• 3/4-16 UNF fine-pitch thread for strong engagement and vibration resistance
• 5/8 inch hex socket drive for use with standard hex keys or Allen drivers
• Fully threaded along the 2-3/4 inch length under head for maximum thread contact
• Alloy steel construction meets ASTM A574 and ASME/ANSI B18.3 standards
• Black oxide coating provides mild corrosion protection and reduced light reflection

Compatibility

Designed as an OEM-style replacement or standard-specification hex socket cap screw for any application requiring a 3/4-16 UNF fully threaded fastener conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated torque wrench with a 5/8 inch hex bit. Always ensure mating threads are clean and free of debris before installation. Power down and de-energize or depressurize any equipment before servicing fasteners in load-bearing or fluid-system assemblies. Do not exceed rated torque values established by the applicable engineering specification for the joint.
