Value Collection -33703-1 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION -33703-1 is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 3/4-10 UNC thread size and measures 7 inches in length under the head. The screw is driven with a 5/8-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and maintains structural integrity under load. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical assemblies where performance and dimensional consistency are required.

This cap screw is used in heavy-duty mechanical and industrial applications where a recessed hex drive is preferred for clean, flush-mount fastening. Typical install scenarios include machine frames, equipment housings, tooling fixtures, and structural steel assemblies. The partial threading provides a stronger grip in thick material applications by ensuring the unthreaded shank spans the joint interface. Machinists, millwrights, and maintenance technicians commonly specify this fastener in production and repair settings.

Key Features

• 3/4-10 UNC thread size for use in standard coarse-thread tapped holes
• 7-inch length under head accommodates thick material stacks and deep fastening applications
• Partially threaded shank improves clamp load distribution across joint interfaces
• 5/8-inch hex socket drive allows high-torque installation with standard hex keys or socket tooling
• Alloy steel construction provides high tensile strength per ASTM A574
• Black oxide finish adds mild corrosion resistance and reduces light reflection in precision assemblies

Compatibility

Designed as an OEM-style replacement or standard-service fastener for industrial assemblies requiring a 3/4-10 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 5/8-inch hex key or socket driver. Ensure the mating tapped hole is clean, properly sized for 3/4-10 UNC, and free of debris before installation. De-energize or lock out any equipment before servicing fastened assemblies per applicable OSHA lockout/tagout procedures. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
