Value Collection 92418 Hex Cap Screw 7/8-9 X 5.5 in 18-8 Ss

Product Description

The VALUE COLLECTION 92418 is a 7/8-9 UNC hex head cap screw measuring 5.5 inches under the head, manufactured from 18-8 stainless steel with no additional coating applied. Partially threaded along its shank, this fastener is suited for applications requiring a bearing surface against the unthreaded portion for accurate clamping force. The 18-8 stainless steel alloy provides corrosion resistance suitable for wet, chemical-exposure, and outdoor environments. Sold in a quantity of 5 per package, this screw follows the inch measurement system and meets standard UNC thread specifications. Licensed tradespeople and maintenance mechanics working in plumbing, HVAC mechanical rooms, pool equipment installations, and general industrial assembly will find this fastener appropriate for structural and equipment-mounting tasks.

This hex head cap screw is used across a wide range of trade and industrial applications including equipment mounting, pipe flange fastening, pump assemblies, and structural connections where corrosion resistance is required. The partial threading design is common in applications where the unthreaded shank must pass through a clearance hole before engaging the threaded section. This screw is appropriate for both interior and exterior installations where stainless steel is specified by design or code requirements.

Key Features

• 7/8-9 UNC thread size for secure engagement with standard inch-series nuts and tapped holes
• 5.5 inches length under head provides adequate grip length for thick materials or stacked assemblies
• 18-8 stainless steel construction offers strong corrosion resistance in wet and outdoor environments
• Partially threaded shank allows precise clamping and shear load distribution
• Uncoated finish maintains base material properties without galvanic risk from plating materials
• Packaged in a quantity of 5 to cover typical single-job fastener requirements

Compatibility

Designed for use with 7/8-9 UNC inch-series hex nuts, washers, and tapped components in standard fastener applications across HVAC, plumbing, pool equipment, and general mechanical assembly.

Installation Notes

Installation is performed by licensed mechanics, pipefitters, or maintenance technicians using a standard hex wrench or socket set sized for 7/8-9 fasteners. Verify mating thread class and material compatibility before installation, particularly in dissimilar-metal assemblies where galvanic corrosion can occur even with stainless fasteners. Follow applicable mechanical or structural codes for torque requirements specific to the joint design. Do not impact-drive stainless steel fasteners, as galling of the threads can result in permanent seizure.
