Value Collection 015545BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 015545BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. It features a 1-8 UNC thread size with a 5.5-inch length under the head and a 0.75-inch hex drive. The screw is partially threaded, making it well suited for applications that require a smooth shank section for close-tolerance alignment or bearing loads. Constructed from alloy steel with a black oxide finish, it delivers strong corrosion resistance and durability under demanding service conditions. The part weighs approximately 1.48 pounds.

This screw is used in a wide range of industrial and mechanical applications where high tensile strength and precise clamping force are required. Typical installation scenarios include machine bases, jigs and fixtures, heavy equipment frames, and structural assemblies. The partially threaded design makes it a common choice when the shank must pass through a clearance hole before engaging threaded material. It is installed by machinists, millwrights, and maintenance technicians working on industrial and commercial equipment.

Key Features

• 1-8 UNC thread size for high load-carrying capacity in coarse-thread applications
• 5.5-inch length under head with partial threading for shank clearance fitment
• 0.75-inch hex socket drive for use with standard hex keys or Allen drive tools
• Alloy steel construction meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards
• Black oxide coating provides moderate corrosion resistance and reduces light reflection

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial assemblies requiring a 1-8 UNC hex socket cap screw with a 5.5-inch length under the head and partial threading per ASME/ANSI B18.3.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or maintenance technician using the appropriate 0.75-inch hex key or drive tool. De-energize and lock out all equipment before fastener removal or installation in live assemblies. Thread engagement should be verified before applying final torque, and mating threads should be inspected for damage or contamination prior to assembly. Black oxide finish provides limited corrosion protection; apply a compatible thread lubricant or sealant if the installation environment involves moisture or chemical exposure.
