Value Collection -33694-1 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION -33694-1 is a hex socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and a clean, uniform appearance. It features a 3/4-10 UNC thread size with 2.25 inches of length under the head, and it is fully threaded along the entire shank. Drive engagement is handled by a 5/8 inch internal hex socket. Licensed mechanics, millwrights, and maintenance technicians commonly install this style of fastener in equipment frames, fixtures, and machine assemblies.

This screw is suited for general industrial and mechanical fastening where a recessed drive head is required to sit flush or below the mating surface. The fully threaded configuration allows maximum thread engagement across the full length under the head, making it a practical choice for through-bolting or threading into deep tapped holes. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, placing it in the medium-to-high strength class for socket cap screws. Typical install scenarios include machine bases, gearbox housings, conveyor frames, and fabricated steel structures.

Key Features

• 3/4-10 UNC thread for compatibility with standard unified coarse-thread tapped holes
• 2.25 inch length under head, fully threaded for maximum engagement
• 5/8 inch internal hex drive for high-torque installation with standard hex keys or socket drivers
• Alloy steel construction for strength under load and vibration
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 3/4-10 UNC fully threaded socket head fastener in alloy steel.

Installation Notes

Installation is performed with a 5/8 inch hex key or T-handle driver rated for the drive size. Ensure the mating tapped hole or nut meets 3/4-10 UNC thread specification before installation. De-energize and lock out any machinery before fastener replacement or torquing operations. Apply thread lubricant or anti-seize compound as required by the service environment to achieve consistent clamp load.
