Value Collection 015547BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 015547BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. This screw features a 1-8 UNC thread and a 6-inch length under the head, making it suitable for thicker material stacks that require deep engagement. Drive is a 3/4-inch internal hex socket, requiring an Allen wrench or hex key of the matching size. Constructed from alloy steel with a black oxide finish, this fastener delivers solid load-bearing performance and moderate corrosion resistance in controlled environments. It conforms to ASME/ANSI B18.3, ASTM A574, and IFI 124 standards.

This screw is used in heavy-duty mechanical, industrial, and manufacturing applications where a recessed drive and high-tensile fastener is required. The partially threaded shank allows for precise clamping force and is well suited for through-bolt configurations, machinery frames, fixture building, and general metal fabrication. Machinists, millwrights, maintenance technicians, and fabricators commonly work with this size and configuration in production and maintenance settings.

Key Features

• 1-8 UNC thread form for use in standard coarse-thread tapped holes
• 6-inch length under head accommodates thick material stacks
• Partially threaded shank for controlled clamping and shear strength
• 3/4-inch hex socket drive for high-torque installation with Allen wrench or hex key
• Alloy steel construction provides high tensile and yield strength
• Black oxide finish offers mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards

Compatibility

Designed as a standard 1-8 UNC hex socket cap screw for use in any application requiring an ASME/ANSI B18.3 or ASTM A574 compliant fastener with a 3/4-inch hex drive and 6-inch grip length.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 3/4-inch hex key or Allen socket with appropriate torque wrench. De-energize and lock out all equipment before fastening into or near live machinery per applicable OSHA lockout/tagout procedures. Ensure mating threads are clean and free of debris before assembly. Do not exceed the torque rating specified by the equipment manufacturer for this thread size and material grade.
