Value Collection R64913499 Hex Cap Screw 1/4-20 X 8 in

Product Description

The VALUE COLLECTION R64913499 is a partially threaded hex head cap screw designed for heavy fastening applications where corrosion resistance and mechanical strength are required. Manufactured from 18-8 stainless steel with an uncoated finish, this fastener measures 1/4-20 thread size at 8 inches under the head. The UNC thread standard ensures broad compatibility with standard tapped holes and nuts. Installers working in plumbing, HVAC equipment mounting, pool equipment enclosures, and general trade fabrication will find this screw suited for assemblies exposed to moisture or mild chemicals.

This cap screw is appropriate for residential and commercial mechanical installations where a corrosion-resistant fastener is specified. The partially threaded shank provides a smooth bearing surface for clamped materials, making it well suited for through-bolt applications with nuts or flange connections where shank engagement matters. It is sold individually with a minimum order quantity of one.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and chemically active environments
• Partially threaded shank allows smooth clamping between fastened materials
• 1/4-20 UNC thread standard for compatibility with widely available nuts and tapped components
• 8-inch length under head accommodates deep stack assemblies and through-bolt applications
• Uncoated finish avoids coating delamination concerns in high-moisture service environments
• Sold individually with no minimum quantity beyond one unit

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw compatible with any tapped hole, standard hex nut, or coupling nut conforming to inch-series UNC fastener specifications.

Installation Notes

Installation should be performed by a qualified technician familiar with fastener torque requirements for 1/4-20 stainless steel hardware. Use appropriately sized hex wrenches or sockets and apply thread lubricant or anti-seize compound when joining stainless to stainless components to prevent galling. De-energize and lock out all electrical, pneumatic, or fluid systems before accessing any assembly requiring fastener replacement. Do not exceed the material yield strength of 18-8 stainless steel by over-torquing during installation.
