Value Collection 3SSC905F0208 Hex Cap Screw 5/16-24 2-1/2 in

Product Description

The VALUE COLLECTION 3SSC905F0208 is a partially threaded hex head cap screw designed for general mechanical fastening applications in trade and industrial settings. It carries a 5/16-24 UNF thread size with a 2-1/2 inch length under head, manufactured from 18-8 stainless steel with no coating applied. The 18-8 grade stainless construction provides solid corrosion resistance, making it suitable for wet, humid, or outdoor environments common in HVAC, plumbing, and equipment installation work. The partially threaded shank allows for clamping force between joined materials without full thread engagement through the entire grip length. Fasteners of this type are standard stock for maintenance, installation, and equipment assembly tasks performed by licensed tradespeople.

This hex head cap screw is well suited for residential and light commercial mechanical system installations where stainless steel fasteners are specified. Typical applications include securing HVAC equipment brackets, plumbing fixture mounts, electrical enclosure assemblies, and general structural connections where corrosion resistance is a priority. The standard inch-series UNF thread pattern is compatible with widely available nuts, threaded inserts, and tapped holes in equipment manufactured to inch-system tolerances. It is sold in a minimum order quantity of 10 units, making it appropriate for both single-job use and small stock replenishment.

Key Features

• 5/16-24 UNF thread for fine-pitch engagement and vibration resistance
• 2-1/2 inch length under head suits medium-grip-length fastening applications
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Partially threaded shank delivers clamping force across unthreaded grip sections
• Uncoated finish maintains dimensional accuracy for close-tolerance tapped holes
• Inch-system measurement throughout for compatibility with standard SAE tooling

Compatibility

Designed as a standard inch-series UNF hex head cap screw for use with 5/16-24 tapped holes, matching nuts, and threaded inserts across mechanical, HVAC, plumbing, and electrical equipment assemblies.

Installation Notes

Install using a standard hex wrench or socket set sized for the hex head drive. Ensure the mating tapped hole or nut matches the 5/16-24 UNF thread specification before installation to avoid cross-threading. Do not exceed the rated torque range appropriate for 18-8 stainless steel fasteners of this diameter, as over-torquing can gall stainless threads. Apply an anti-seize compound if fasteners will be exposed to high heat or saltwater environments to ease future removal.
