Value Collection 1-H-87C-150 Hex Head Cap Screw

Product Description

The VALUE COLLECTION 1-H-87C-150 is a 7/8-9 hex head cap screw machined from 18-8 stainless steel. It measures 1-1/2 inches under the head and features a 1-5/16 inch hex drive. The 7/8-9 thread designation indicates a 7/8 inch nominal diameter with 9 threads per inch on a Unified National Coarse (UNC) standard. The 18-8 stainless steel construction provides solid corrosion resistance in wet, chemical-exposure, and outdoor environments. This fastener is a standard component used across mechanical, structural, and process-equipment assemblies by pipefitters, millwrights, plumbers, and general mechanical contractors.

This cap screw is suited for general industrial and trade applications where a corrosion-resistant, heavy-hex fastener is required. Typical installations include flanged pipe assemblies, equipment mounting, structural connections, and pump or valve assembly work. The UNC thread form makes it compatible with standard tapped holes and hex nuts of the same pitch and diameter. It is sold individually but carries a minimum order quantity of 5 units.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and chemical-exposure environments
• 7/8-9 UNC thread — standard Unified National Coarse pitch for broad compatibility with off-the-shelf nuts and tapped holes
• 1-1/2 inch length under head for precise grip-length control in structural and mechanical assemblies
• 1-5/16 inch hex drive compatible with standard open-end, box, and socket wrenches
• Inch measurement system throughout — no conversion required for domestic trade work

Compatibility

Designed as a standard UNC hex head cap screw for use with any 7/8-9 tapped hole or matching hex nut; no specific model or equipment compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or millwright using a properly sized 1-5/16 inch wrench or socket. Always degrease mating threads before installation, and apply anti-seize compound if the fastener will be exposed to high heat or highly corrosive conditions to prevent galling in stainless-to-stainless applications. Do not exceed the rated mechanical limits of 18-8 stainless steel in high-load structural applications without engineering review. Follow applicable codes and equipment manufacturer torque specifications for the assembly being serviced.
