Value Collection 3SSC907F0400 Hex Head Cap Screw 7/16-20

Product Description

The VALUE COLLECTION 3SSC907F0400 is a partially threaded hex head cap screw used in mechanical assembly, structural fastening, and equipment fabrication across a wide range of trades. It features a 7/16-20 UNF thread form, a 4-inch length under head, and a 5/8-inch hex drive. Constructed from Grade 18-8 stainless steel with no coating applied, this screw provides solid corrosion resistance in wet, outdoor, or chemically exposed environments. The partial thread design allows for clamping force on unthreaded shanks, which is standard practice for bolted joint assemblies where shear load transfer is a factor.

This fastener is suited for use in HVAC equipment panels, plumbing fixture mounting, pool equipment enclosures, and general industrial assembly where a fine-thread stainless cap screw is specified. The 7/16-20 UNF pitch is a fine-thread designation that provides greater thread engagement per inch compared to coarse-thread equivalents, making it appropriate for applications requiring precise torque control or vibration resistance. Installers working in marine, chemical, or outdoor settings commonly select 18-8 stainless for its balance of strength and oxidation resistance.

Key Features

• 7/16-20 UNF fine-thread form for strong thread engagement and vibration resistance
• 4-inch length under head with partial threading for proper shank-to-joint clamping
• 5/8-inch hex drive compatible with standard hex wrenches and sockets
• Grade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• Uncoated finish — no plating or treatment that could affect dimensional tolerance or chemical compatibility

Compatibility

Designed as a standard UNF hex head cap screw for use in any application calling for a 7/16-20 fine-thread fastener with a 4-inch length under head and 18-8 stainless steel material.

Installation Notes

Installation should be performed by a qualified mechanic, technician, or installer familiar with bolted joint specifications. De-energize and depressurize any equipment before fastener replacement or assembly work. Use a properly sized 5/8-inch hex wrench or socket to avoid fastener damage; do not use an adjustable wrench where torque accuracy is required. Follow the torque specifications defined by the equipment manufacturer or applicable engineering standard for the joint being assembled.
