Value Collection R88448941 Hex Head Cap Screw 7/8-9 X 10 in

Product Description

The VALUE COLLECTION R88448941 is a partially threaded hex head cap screw in the 7/8-9 UNC thread size with a 10-inch length under head. Manufactured from 18-8 stainless steel and left uncoated, this fastener delivers solid corrosion resistance in wet, chemical-exposure, and outdoor environments. The partial threading provides a smooth shank section that can improve shear strength and alignment in structural and mechanical assemblies. Plumbers, pipefitters, millwrights, and maintenance technicians working on equipment frames, flanges, and structural connections reach for this grade of fastener where corrosion resistance is a priority.

This screw is suited for use in industrial, commercial, and mechanical applications where a large-diameter, coarse-thread fastener is required. Typical installations include equipment base plates, pump and motor mounts, pipe support structures, and heavy fabrications. The 7/8-9 UNC coarse thread offers reliable engagement in standard tapped holes and is a common size in machinery and structural work across HVAC, plumbing, and general industrial trades.

Key Features

• 18-8 stainless steel construction provides corrosion and oxidation resistance without a surface coating
• 7/8-9 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 10-inch length under head accommodates thick flanges, stacked components, and deep assemblies
• Partial threading leaves a smooth shank that helps resist shear loads and aids part alignment
• Uncoated finish is suitable for environments where coatings may be incompatible with process fluids or chemicals

Compatibility

Designed for use in any application requiring a 7/8-9 UNC hex head cap screw with a 10-inch length under head in 18-8 stainless steel. Fits standard 7/8-9 UNC tapped holes and is used with matching hex nuts and washers.

Installation Notes

Installation should be performed by a qualified tradesperson using an appropriate socket or wrench sized for the hex head. Always verify the mating tapped hole or nut is the correct 7/8-9 UNC thread standard before driving the fastener. De-energize or depressurize any equipment before fastener service. Apply anti-seize compound when connecting stainless fasteners to stainless threads to prevent galling during torque-up.
