Value Collection 353-0506-01 Button Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 353-0506-01 is a button socket cap screw designed for fastening applications that require a low-profile head and a secure, high-strength connection. Made from alloy steel with a black oxide finish, this screw offers corrosion resistance and a clean appearance suitable for exposed or semi-exposed assemblies. The Torx Plus IP40 drive resists cam-out under high torque, making it a reliable choice for precision mechanical assemblies. It is fully threaded with a 5/16-18 UNC thread in a 3A fit class and meets ANSI/ASME B18.3 and ASTM F835 standards. Machinists, maintenance technicians, and fabricators are the typical installers.

This screw is suited for light to medium industrial, commercial, and OEM manufacturing applications where a flush or low-profile fastener head is required. The 3/8-inch length under head makes it appropriate for thin-material fastening in machinery, enclosures, fixtures, and structural assemblies. The black oxide finish blends into finished surfaces and provides mild protection against oxidation in dry or lightly humid environments.

Key Features

• Torx Plus IP40 drive reduces cam-out and allows higher torque transfer compared to hex socket drives
• Alloy steel construction with 39-44 HRC hardness for high shear and tensile strength
• Black oxide coating provides a corrosion-resistant, low-reflectance finish
• Fully threaded 5/16-18 UNC right-hand thread in 3A fit class for precise engagement
• Button head profile keeps the fastener low-profile in finished assemblies
• Meets ANSI/ASME B18.3 and ASTM F835 standards for dimensional and mechanical conformance

Compatibility

Designed as a standard replacement or OEM-style fastener for applications requiring a 5/16-18 UNC button socket cap screw with a Torx Plus IP40 drive and a 3/8-inch length under head.

Installation Notes

This fastener is typically installed by machinists, maintenance technicians, or assembly workers using a calibrated IP40 Torx Plus bit or driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the mechanical limits of the alloy steel construction or the mating material. Follow applicable industry torque guidelines for 5/16-18 fasteners in the relevant material class.
