Value Collection R63038440 Hex Head Cap Screw 5/16-24

Product Description

The VALUE COLLECTION R63038440 is a hex head cap screw manufactured from 18-8 stainless steel with a 5/16-24 UNF (Unified Fine) thread form. It measures 3/4 inches under the head and accepts a 1/2-inch hex drive. The 18-8 stainless steel construction provides solid corrosion resistance for general industrial, mechanical, and trade service applications. Installed with a standard hex wrench or socket, this fastener suits light-to-medium fastening tasks where corrosion resistance and dimensional accuracy are required. Maintenance technicians, service contractors, and tradespeople working on equipment assemblies commonly stock this size.

This fastener applies to a broad range of mechanical assembly and equipment service work. The 5/16-24 UNF thread is a fine-thread configuration, making it well suited for applications where vibration resistance or precise torque control is important. It is commonly used in HVAC equipment panels, pump housings, brackets, and general mechanical assemblies that call for inch-series stainless fasteners. Sold individually per package, with a minimum order quantity of 100 pieces.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or outdoor service environments
• 5/16-24 UNF fine-thread form for improved vibration resistance over coarse-thread equivalents
• 3/4-inch length under head suits standard panel and bracket fastening applications
• 1/2-inch hex drive compatible with standard hex keys and sockets
• Inch system of measurement; fully compatible with standard UNF tooling and thread gauges

Compatibility

Designed as a standard inch-series UNF hex head cap screw for use in any mechanical assembly or equipment application calling for a 5/16-24 x 3/4-inch stainless steel fastener.

Installation Notes

Install and remove using a properly sized 1/2-inch hex wrench or socket to avoid rounding the fastener head. Ensure the mating threaded hole is clean and free of debris before driving the screw. Do not mix stainless steel fasteners with dissimilar metals in highly corrosive environments without accounting for galvanic compatibility. Apply thread lubricant or anti-seize compound as required by the equipment manufacturer's service documentation.
