Value Collection 88547203 Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 88547203 is a 7/8-9 UNC hex socket cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and a consistent, low-reflectance appearance suitable for general industrial use. The screw measures 2 inches under the head and is fully threaded, accepting a 3/4-inch hex drive. It is suited for applications where a recessed drive fastener is required to keep hardware flush or below the work surface. Machinists, millwrights, and maintenance technicians are the typical installers of this fastener type.

This hex socket cap screw is appropriate for use in machinery maintenance, fixture fabrication, and structural connections where 7/8-9 UNC threading is specified. Full threading along the 2-inch shank length provides maximum thread engagement across the entire grip range. The black oxide coating is compatible with lightly oiled assemblies and is commonly found in industrial, OEM, and MRO environments. This fastener is sold individually and is well-suited for low-quantity repair and replacement jobs where a single piece is needed.

Compatibility

Designed as a standard 7/8-9 UNC hex socket cap screw for use in any assembly or fixture calling for this thread size, drive type, and fastener length.

Installation Notes

Installation requires a 3/4-inch hex key or socket driver rated for the torque requirements of 7/8-9 fasteners. De-energize, depressurize, or lock out the equipment before servicing any assembly this fastener secures. Follow applicable mechanical and structural codes for torque specifications based on fastener grade and joint material. Applying a thread lubricant or anti-seize compound is common practice in high-vibration or dissimilar-metal assemblies.
