Value Collection MP33683-1 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION MP33683-1 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 5/8-11 UNC thread and a 2-inch length under head with full threading along the entire shank. Drive engagement is through a 1/2-inch hex socket, which provides high torque transfer and reduces the risk of drive slippage. The alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards, and the black oxide finish provides a baseline level of corrosion resistance for indoor and protected environments.

This cap screw is suited for use in machine assembly, die and mold work, equipment maintenance, and structural fastening where socket-drive access is required. The fully threaded 5/8-11 UNC configuration allows engagement along the full shank length, making it appropriate for through-hole and shallow-clearance applications. It is commonly installed by machinists, maintenance technicians, and mechanical contractors working on industrial machinery, brackets, and fabricated steel assemblies.

Key Features

• 5/8-11 UNC thread for high clamping load in standard inch-series applications
• Fully threaded shank allows maximum thread engagement across the 2-inch length under head
• 1/2-inch hex socket drive enables high-torque installation with standard Allen keys or socket drivers
• Alloy steel construction conforms to ASTM A574 for tensile strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies
• Meets ASME/ANSI B18.3 dimensional standards for consistent fitment

Compatibility

Designed as an OEM-style replacement or standard service fastener for industrial machinery, fabricated assemblies, and equipment requiring 5/8-11 UNC inch-series socket cap screws per ASME/ANSI B18.3.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician using a properly sized 1/2-inch hex key or socket driver. De-energize and lock out all equipment before servicing fastened assemblies per applicable OSHA lockout/tagout procedures. Inspect mating threads for damage or contamination before installation. Do not use impact drivers on alloy socket cap screws without a verified torque-limiting method.
