Value Collection 011513BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 011513BR is a hex socket cap screw designed for high-strength fastening in structural, mechanical, and industrial assemblies. This screw features a 7/8-9 UNC thread size and measures 5 inches in length under the head with partial threading along the shank. The 3/4-inch hex drive accommodates standard hex keys and socket drivers. Manufactured from alloy steel and finished with a black oxide coating, it provides corrosion resistance and a low-reflectance surface. Compliant with ASME/ANSI B18.3 and ASTM A574 standards, this fastener meets the mechanical requirements expected in demanding trade and industrial applications.

This cap screw is suited for use in machinery, equipment frames, structural steel connections, and general industrial assemblies where a high-strength threaded fastener is required. The partial threading is appropriate for applications that require a smooth shank section for alignment or shear load transfer. Maintenance technicians, millwrights, and industrial mechanics commonly install this type of fastener in both original equipment and field repair scenarios.

Key Features

• 7/8-9 UNC thread for broad compatibility with standard tapped holes
• 5-inch length under head with partial threading for shear and alignment applications
• 3/4-inch hex socket drive compatible with standard hex keys and drive sockets
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish provides mild corrosion resistance and reduced surface reflectance
• Meets ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in tapped holes or with compatible nuts in industrial and mechanical assemblies requiring 7/8-9 UNC threading.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a properly sized 3/4-inch hex key or socket drive tool. De-energize and lock out any equipment before installing or removing fasteners in powered machinery. Do not exceed the rated torque for the thread size and material grade; consult engineering references for the applicable torque specification for ASTM A574 alloy steel fasteners. Inspect the tapped hole for thread condition and cleanliness before installation.
