Value Collection 353-2616-01 Button Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 353-2616-01 is a fully threaded button socket cap screw designed for fastening applications that require a low-profile head and a secure, high-torque drive interface. Built from alloy steel with a black oxide finish, this screw offers corrosion resistance and a hardness rating of 39-44 HRC, making it suitable for demanding mechanical assemblies. It features a Torx Plus IP45 drive, which reduces cam-out and allows higher torque transmission compared to standard hex socket drives. The 3/8-24 thread is a fine-pitch Unified National Right-Hand Fine (UNRF) thread, conforming to ANSI/ASME B18.3 and ASTM F835 standards.

This button socket cap screw is used in mechanical, industrial, and OEM assembly applications where a flush or semi-flush fastener profile is preferred. The fine 3/8-24 thread pitch provides greater thread engagement per inch, which is advantageous in applications requiring vibration resistance or precise clamping force. It is commonly installed by machinists, millwrights, and maintenance technicians working on machinery enclosures, fixtures, brackets, and structural assemblies. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• Torx Plus IP45 drive for high torque transmission and reduced cam-out
• Alloy steel construction with 39-44 HRC hardness for strength in demanding assemblies
• Black oxide finish for moderate corrosion resistance and low-glare appearance
• Fine-pitch 3/8-24 UNRF thread for increased vibration resistance
• Fully threaded along the 1-inch length under head
• Conforms to ANSI/ASME B18.3 and ASTM F835 standards

Compatibility

Designed as a standard replacement or OEM-style fastener for applications specifying a 3/8-24 button socket cap screw per ANSI/ASME B18.3 and ASTM F835. Verify thread class 3A fit with mating components before installation.

Installation Notes

Installation requires a Torx Plus IP45 bit or driver; do not substitute a standard Torx T27 bit, as it may damage the drive recess. Follow applicable torque specifications from the equipment manufacturer or a fastener engineering reference for 3/8-24 alloy steel cap screws at the appropriate hardness grade. Thread fit class is 3A, so confirm the mating thread is class 3B before assembly. Minimum order quantity is 100 pieces per order increment.
