Value Collection 015299PR Hex Head Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 015299PR is a partially threaded hex head cap screw manufactured from alloy steel with a black oxide finish. It carries a 3/8-24 thread size and measures 2 inches under the head. The black oxide coating provides moderate corrosion resistance and reduces light reflection, making it a common choice in machinery, tooling fixtures, and mechanical assemblies. The 5/16-inch hex drive accepts standard hex keys and allen wrenches. This fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, confirming tensile and hardness requirements for high-strength socket-drive applications. Machinists, millwrights, and maintenance technicians typically specify this style of cap screw for precision fastening work.

This cap screw is suited for industrial and mechanical applications where a high-strength, close-tolerance fastener is required. Partially threaded shanks provide clamping load along the unthreaded portion and are preferred when the joint requires a defined grip length. Typical use cases include fixturing, machine tool assembly, and structural mechanical connections. The alloy steel construction handles elevated stress loads where low-carbon or stainless fasteners would be undersized. Minimum order quantity is 10 units.

Key Features

• 3/8-24 fine thread provides tighter thread engagement and higher resistance to loosening under vibration
• Partially threaded shank maintains a clean grip zone for precise joint clamping
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish reduces surface corrosion and minimizes glare in precision environments
• 5/16-inch hex drive compatible with standard hex keys and socket tooling
• Complies with ASME/ANSI B18.3 and IFI 124 dimensional and performance standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex head cap screw suitable for industrial machinery, tooling, and mechanical assemblies requiring a 3/8-24 fine-thread partially threaded fastener.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5/16-inch hex key or socket driver. Always de-energize and lock out equipment before fastener installation or removal in mechanical assemblies. Do not mix thread classes or force engagement in misaligned holes, as this can damage thread form and compromise joint integrity. Verify torque requirements against the assembly specification or applicable engineering standard before final tightening.
