Value Collection -33699-4 Hex Socket Cap Screw 3/4-10

Product Description

The VALUE COLLECTION -33699-4 is a partially threaded hex socket cap screw engineered for high-strength fastening applications across industrial, mechanical, and structural assemblies. The screw features a 3/4-10 UNC thread size and a 4-inch length under head, making it suitable for thick-material clamping where a full-thread design would not achieve proper clamp load. Drive engagement is through a 5/8-inch internal hex socket. The alloy steel construction is finished with a black oxide coating that provides mild corrosion resistance and a uniform appearance. Installation requires a calibrated torque wrench or hex key driver of the correct drive size.

This cap screw is used in general industrial maintenance, machine assembly, tooling fixtures, and structural bolt-up work where a recessed-drive fastener is required. The partially threaded shank provides a shoulder bearing surface, which is particularly useful in applications involving shear loads or precise hole alignment. Trades and maintenance technicians working on heavy equipment, presses, conveyor systems, or fabricated steel structures will commonly encounter this fastener specification.

Key Features

• 3/4-10 UNC thread form for compatibility with standard inch-series tapped holes
• 4-inch length under head with partial threading for shear-load and bearing-surface applications
• 5/8-inch internal hex drive for high-torque installation with standard hex keys or socket drivers
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish provides mild corrosion resistance and reduces surface glare

Compatibility

Designed as an OEM-style replacement or maintenance fastener for any application 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 should be performed by a qualified mechanic or maintenance technician familiar with inch-series fastener torque requirements. Always clean and inspect the tapped hole before installation, and ensure the drive tool is fully seated in the hex socket to avoid rounding. De-energize and lock out all equipment before servicing any fastener in a live mechanical assembly. Consult the equipment manufacturer's torque specification table for the applicable clamp load for this thread size and material grade.
