Value Collection 88547260 Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 88547260 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This screw features a 7/8-9 UNC thread size and measures 6 inches in length under the head. It is driven with a 3/4-inch hex key and is partially threaded along its shank. Constructed from alloy steel with a black oxide coating, it delivers solid corrosion resistance and maintains the tensile strength expected from alloy-grade fasteners. Machinists, millwrights, maintenance technicians, and general contractors install this type of fastener in equipment assemblies, fixtures, and structural connections.

This cap screw is suited for applications requiring a partially threaded, high-strength socket drive fastener. The 7/8-9 UNC coarse thread pitch provides reliable engagement in steel and cast-iron tapped holes. Typical install scenarios include machine bases, heavy equipment frames, jigs, fixtures, and structural steel assemblies. The black oxide finish reduces surface friction and provides mild protection against moisture and oxidation in indoor or sheltered environments.

Key Features

• 7/8-9 UNC coarse thread for reliable engagement in tapped alloy and cast-iron holes
• 6-inch length under head accommodates thick material stacks and deep clearance bores
• Partially threaded shank improves shear strength and alignment in close-tolerance holes
• 3/4-inch hex drive accepts standard hex keys and socket tooling
• Alloy steel construction provides high tensile and yield strength
• Black oxide coating reduces light corrosion and minimizes galling during installation

Compatibility

Designed as a direct-fit replacement or standard cap screw for applications requiring a 7/8-9 UNC partially threaded hex socket cap screw in alloy steel.

Installation Notes

Installation should be performed by a qualified technician using a calibrated torque wrench and a properly sized 3/4-inch hex key or socket bit. Verify that the mating tapped hole meets the correct UNC thread specification and is free of debris before driving the fastener. Follow applicable ASME or equipment manufacturer torque guidelines for the fastener grade and material stack. Do not exceed the rated drive torque for the alloy steel grade used in this screw.
