Value Collection 209108 Hex Head Cap Screw 7/8-9 18-8 Ss

Product Description

The VALUE COLLECTION 209108 is a hex head cap screw designed for general industrial and mechanical fastening applications. It features a 7/8-9 UNC thread profile and measures 3-1/2 inches under the head, making it suitable for medium-to-heavy-duty bolted assemblies. Constructed from 18-8 stainless steel, this fastener offers good corrosion resistance in mildly corrosive and outdoor environments. The 1-5/16 inch hex drive allows installation with standard hex wrenches or socket sets. This screw is commonly installed by millwrights, pipefitters, electricians, plumbers, and HVAC technicians during equipment mounting, structural assembly, and bracket work.

This hex head cap screw is appropriate for a wide range of trade and industrial applications where a coarse-thread stainless fastener is required. Typical use cases include equipment base mounting, flange bolting, panel attachment, and structural connections in environments where mild corrosion resistance is needed. The UNC thread standard ensures compatibility with standard inch-series tapped holes and hex nuts across commercial and residential construction, mechanical rooms, and industrial facilities.

Key Features

• 7/8-9 UNC coarse thread for reliable engagement in standard inch-series tapped holes
• 3-1/2 inch length under head accommodates medium stack-up thicknesses in bolted assemblies
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor service
• 1-5/16 inch hex head fits standard wrenches and socket sets
• Inch measurement system for straightforward compatibility with standard fastener hardware

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 7/8-9 UNC tapped hole or matching hex nut in typical mechanical and structural assemblies.

Installation Notes

Install using a properly sized 1-5/16 inch hex wrench or socket. Power down or de-energize any equipment before fastening components in electrical or HVAC assemblies. Apply appropriate thread lubricant or anti-seize compound when installing stainless steel fasteners into stainless or dissimilar metal threads to reduce the risk of galling. Follow applicable torque specifications from the equipment manufacturer or relevant codes such as ASME or AISC for structural applications.
