Value Collection 581736BR Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION 581736BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 3/4-16 UNF thread size and measures 3-1/2 inches in length under the head, with partial threading. The 5/8-inch hex drive accepts a standard Allen or hex key for installation. Constructed from alloy steel with a black oxide finish coating, the fastener provides corrosion resistance suitable for dry and lightly oiled environments. Mechanical contractors, millwrights, and maintenance technicians commonly install this type of fastener in both production and repair settings.

This socket cap screw is appropriate for use in close-tolerance applications where a flush or recessed fastener head is required. The 3/4-16 UNF fine thread pitch delivers high clamping force and resistance to vibration loosening, making it well suited for machine bases, hydraulic components, and structural assemblies. Fine-thread fasteners of this type are common in both OEM manufacturing and field maintenance work where thread engagement quality and torque retention are critical. This item is sold individually with a minimum order quantity of 10 units.

Key Features

• 3/4-16 UNF fine thread for high clamping load and vibration resistance
• 3-1/2 inch length under head with partial threading
• 5/8-inch hex socket drive for Allen key or hex bit installation
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish coating for mild corrosion protection and reduced light reflection
• Partially threaded shank allows for precise shoulder-bearing load transfer

Compatibility

Designed as an OEM-style replacement or stock fastener for industrial machinery, fixtures, and mechanical assemblies requiring 3/4-16 UNF hex socket cap screws conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is typically performed by a machinist, millwright, or maintenance technician using a 5/8-inch hex key or socket drive. Always verify thread engagement depth and mating material compatibility before final torque. Clean threads and apply appropriate thread lubricant or anti-seize compound per the assembly specification before installation. Power down and de-energize or depressurize the assembly before servicing any fasteners in live mechanical or hydraulic systems.
