Value Collection 015429BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 015429BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, manufacturing, and mechanical assembly environments. It features a 5/8-11 UNC thread size and a 3-1/2 inch length under the head, with a 1/2 inch hex drive socket for use with standard Allen or hex key tools. Constructed from alloy steel and finished with a black oxide coating, this fastener delivers solid corrosion resistance and reduced surface glare. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards. Machinists, millwrights, and maintenance technicians commonly specify this screw for demanding structural and mechanical fastening tasks.

This hex socket cap screw is suited for general industrial assembly, machine building, tooling fixtures, and equipment maintenance where a flush or recessed fastener head is required. The partial threading allows for better clamping load distribution in thick material joints. The 5/8-11 UNC coarse thread profile is widely used in standard inch-series applications across manufacturing facilities, fabrication shops, and field service environments. It is installed using a 1/2 inch hex key or socket driver.

Key Features

• 5/8-11 UNC coarse thread for compatibility with standard inch-series tapped holes
• 3-1/2 inches length under head for deep fastening in thick material sections
• Partially threaded shank for improved clamping force in bolted joints
• Alloy steel construction for high tensile strength and durability
• Black oxide finish provides mild corrosion resistance and low-reflectance surface
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard replacement or new-installation hex socket cap screw for any application requiring a 5/8-11 UNC partially threaded fastener with a 1/2 inch hex drive in industrial and mechanical assemblies.

Installation Notes

Install using a 1/2 inch hex key or Allen driver; ensure the mating tapped hole is clean and free of debris before driving. De-energize and lock out any machinery before replacing fasteners on live equipment in accordance with applicable OSHA lockout/tagout procedures. Do not over-torque; consult appropriate ASME torque tables for 5/8-11 alloy steel fasteners at the applicable grade. Inspect threads for damage before installation and replace any screw showing galling or deformation.
