Value Collection 011515BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 011515BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assembly work. Manufactured from alloy steel with a black oxide coating, this cap screw delivers corrosion resistance alongside the tensile strength required for demanding bolted joints. The 7/8-9 UNC thread form provides a coarse-pitch profile suited to general industrial use, while the 3/4-inch hex drive accommodates standard hex keys and socket drives. At 5-1/2 inches in length under the head and partially threaded, it is well matched to applications requiring grip length control in thicker workpieces. Machinists, millwrights, and maintenance mechanics are the typical installers.

This cap screw is suited for use in machine assembly, equipment mounting, fixture building, and structural bolted connections where a recessed hex drive and high-strength alloy construction are required. Partial threading allows the unthreaded shank to act as a pilot or provide bearing surface in clearance holes. The black oxide finish offers moderate corrosion resistance in indoor or controlled environments and reduces light reflection in precision equipment. Conformance to ASME/ANSI B18.3 and ASTM A574 standards makes this fastener appropriate for specified engineering applications.

Key Features

• 7/8-9 UNC coarse-thread profile for broad industrial compatibility
• 5-1/2 inch length under head with partial threading for grip-length control
• 3/4-inch hex socket drive for use with standard hex keys and socket tools
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide coating provides moderate corrosion resistance and a low-glare finish
• Meets ASME/ANSI B18.3 dimensional standards for consistent fitment

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial machinery, structural assemblies, and mechanical equipment requiring a 7/8-9 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance mechanics using a 3/4-inch hex key or socket drive. De-energize and lock out all equipment before fastener removal or installation per applicable OSHA lockout/tagout procedures. Ensure mating threads are clean and free of debris before driving. Do not exceed the rated clamp load for the joint material and thread engagement length specified in the engineering design.
