Value Collection R88412602 Hex Head Cap Screw 316 Ss

Product Description

The VALUE COLLECTION R88412602 is a 1-8 x 8 inch partially threaded hex head cap screw machined from Grade 316 stainless steel with an uncoated finish. It follows the Unified National Coarse (UNC) thread standard and is measured length-under-head. Grade 316 stainless provides strong resistance to corrosion and pitting, making it well suited for wet, chemical, or marine environments. The large 8 inch length accommodates deep fastening applications where standard-length hardware falls short. Installers and maintenance technicians working in demanding environments rely on this grade for long-term fastener integrity without coating degradation.

This cap screw is used in industrial, commercial, and mechanical assembly applications where corrosion resistance is a primary concern. Typical installations include pipe flanges, pump housings, HVAC equipment mounting, and structural assemblies exposed to moisture or mild chemicals. The partial threading allows for a smooth shank section that resists shear loads and provides a cleaner grip in through-bolt applications. It is appropriate for both new construction and field maintenance work performed by pipefitters, millwrights, mechanical contractors, and HVAC technicians.

Key Features

• Grade 316 stainless steel construction for superior corrosion and pitting resistance
• 1-8 UNC thread size with partial threading for shear-load capability
• 8 inch length under head for deep fastening applications
• Uncoated finish eliminates risk of coating failure in harsh environments
• Hex head drive for standard wrench and socket tool compatibility

Compatibility

Designed as a standard UNC hex head cap screw for use in applications requiring a 1-8 thread size and 8 inch length under head in Grade 316 stainless steel.

Installation Notes

Installation should be performed by qualified mechanical, plumbing, or HVAC technicians using appropriate hex wrenches or impact sockets rated for the fastener size. Ensure mating threads are clean and free of debris before driving. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or high-humidity environments to prevent galvanic corrosion. Apply an anti-seize compound to stainless threads when specified by the assembly procedure, as stainless fasteners are susceptible to galling under high torque without lubrication.
