Value Collection 2-S-31F-100 Hex Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION 2-S-31F-100 is a hex socket cap screw designed for secure, high-torque fastening in applications where a low-profile head and internal hex drive are required. It features a 5/16-24 UNF thread and measures 1 inch in length under the head. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this fastener delivers strong corrosion resistance in wet, chemical, or marine environments. It accepts a 1/4-inch hex drive tool. Installation is performed using a standard hex key or Allen-style driver. This screw is suited for mechanical assemblies, equipment fabrication, and maintenance work across HVAC, plumbing, electrical, and general trade applications.

This fastener is appropriate for residential and commercial installations where a fine-thread socket cap screw is specified. The 5/16-24 UNF thread pitch provides superior thread engagement and vibration resistance compared to coarse-thread equivalents. Grade 316 stainless construction makes it a practical choice in environments exposed to moisture, mild acids, or chlorides. Tradespeople and fabricators install this screw wherever a tamper-resistant, recessed-drive fastener is called for in light structural or mechanical assemblies.

Compatibility

Designed as a standard 5/16-24 UNF hex socket cap screw suitable for general mechanical assemblies, equipment panels, and trade installations requiring a fine-thread, Grade 316 stainless fastener.

Installation Notes

Install using a 1/4-inch hex key or Allen-style driver torqued to the fastener specification for the mating material. Ensure mating threads are clean and free of debris before installation. Do not cross-thread; hand-start the screw before applying drive torque. Follow applicable mechanical or structural codes for the assembly being serviced.
