Value Collection 581718BR Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION 581718BR 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 — a fine-pitch thread that delivers strong clamping force and resistance to loosening under vibration. The 3/8-inch hex drive accepts a standard Allen key or hex bit driver. The fastener is manufactured from alloy steel and finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection on exposed surfaces. It meets ASME/ANSI B18.3 and ASTM A574 standards, confirming compliance with recognized dimensional and mechanical property requirements for socket cap screws.

This screw is suited for precision mechanical work where fine-thread engagement and controlled torque are required. Typical applications include machine tool mounting, hydraulic component assembly, jig and fixture fabrication, and general industrial maintenance. The fully threaded shank provides maximum thread engagement across the full length under the head, making it well-suited for shorter through-hole or tapped-hole installations. This item is sold individually but requires a minimum order quantity of 10 units.

Key Features

• 3/4-16 UNF fine-pitch thread for high clamping load and vibration resistance
• 1-1/4 inch length under head, fully threaded
• 3/8-inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish for mild corrosion resistance and low-glare appearance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any tapped or through-hole application requiring a 3/4-16 UNF fine-thread fastener.

Installation Notes

Installation requires a 3/8-inch hex key or Allen-type bit driver. Verify that the mating tapped hole is cut to 3/4-16 UNF specification before installation to avoid cross-threading. Ensure mating surfaces are clean and free of debris before seating the fastener. Follow applicable torque specifications for ASTM A574 alloy steel socket cap screws as referenced in engineering documentation or standard fastener torque tables.
