Value Collection -33704-1 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION -33704-1 is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 3/4-10 UNC with an 8-inch length under head, this fastener is driven by a 5/8-inch hex (Allen) key. Constructed from alloy steel with a black oxide finish, it meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding load-bearing joints where tensile strength and corrosion resistance are required. Each package contains 5 screws.

This screw is well suited for heavy machinery assembly, jig and fixture construction, and general industrial fabrication where a recessed drive fastener is preferred over a hex head bolt. Partial threading allows for precise clamping force on through-bolted connections and is commonly specified in maintenance, repair, and original equipment manufacturing contexts. Installers working in shops, plants, or field fabrication environments will find this fastener appropriate for metal-to-metal joint applications.

Key Features

• 3/4-10 UNC thread size for standard coarse-thread compatibility
• 8-inch length under head — partially threaded for accurate clamping
• 5/8-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener specifications
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 3/4-10 UNC coarse-thread socket cap screw for use in metal assemblies, fixtures, and equipment where ASME/ANSI B18.3 and ASTM A574 compliant fasteners are specified.

Installation Notes

Installation is performed using a 5/8-inch hex key or hex socket bit driver. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the engineering documentation or equipment manufacturer for 3/4-10 alloy steel fasteners. Always use appropriate personal protective equipment when working with heavy fasteners in industrial environments.
