Value Collection 011433BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 011433BR is a partially threaded hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and trade environments. It carries a 5/8-11 UNC thread size and measures 4.5 inches in length under the head. Driven with a 1/2-inch hex key, the screw is manufactured from alloy steel and finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection. Licensed tradespeople and maintenance technicians use this fastener in structural assemblies, machinery mounting, and equipment fabrication where tensile strength and precise thread engagement are critical.

This screw is suited for use in heavy mechanical assemblies, manufacturing fixtures, and equipment installations where a recessed drive is preferred to reduce fastener head profile and allow flush or countersunk seating. The 5/8-11 UNC thread form is a standard coarse-thread specification compatible with tapped holes and nuts conforming to ASME/ANSI B18.3 and ASTM A574 standards. It is a common choice in industrial maintenance, millwright work, and general mechanical contracting.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes and hex nuts
• 4.5-inch length under head accommodates deeper through-hole and clamping applications
• Partially threaded shank provides a stronger grip zone and improved shear resistance
• Alloy steel construction meets ASTM A574 requirements for high-strength socket cap screws
• Black oxide finish offers mild corrosion resistance and a low-reflectance appearance
• 1/2-inch hex drive accepts standard hex keys and socket drive tooling

Compatibility

Designed as a standard ASME/ANSI B18.3 and ASTM A574 compliant hex socket cap screw suitable for use in any application requiring a 5/8-11 UNC partially threaded fastener with a 1/2-inch internal hex drive.

Installation Notes

Installation should be performed by qualified mechanical technicians or tradespeople using a calibrated 1/2-inch hex key or socket driver. Ensure the mating tapped hole or nut meets the same 5/8-11 UNC thread specification before installation. De-energize or lock out any equipment per OSHA lockout/tagout procedures before fastening or removing hardware in powered assemblies. Do not exceed the fastener's rated torque capacity; consult a torque specification reference appropriate to the alloy steel grade and lubrication condition.
