Value Collection 015243PR Hex Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION 015243PR is a partially threaded hex socket cap screw designed for applications requiring a precise, high-strength fastener in tight spaces. Manufactured from alloy steel with a black oxide finish, this screw measures 2.25 inches in length under the head and accepts a 0.25-inch hex drive. The black oxide coating provides mild corrosion resistance and reduces light reflection in service environments. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for mechanical assemblies, machinery, and structural connections where dimensional and material traceability matter. Installation is performed using a standard hex key or Allen driver. Machinists, millwrights, and maintenance technicians are the primary installers.

This fastener is suited for industrial and mechanical assembly work where a 5/16-24 UNF fine-thread profile is specified. Fine-thread fasteners are commonly used in applications requiring higher tensile load capacity or finer torque control compared to coarse-thread equivalents. The partial threading allows for a smooth shank section, which is useful in clearance holes or pivot applications. This screw is appropriate for use in machinery, fixtures, tool and die work, and general fabrication where alloy steel strength and a controlled finish are required.

Key Features

• 5/16-24 UNF fine-thread profile for higher thread engagement and load capacity
• 2.25-inch length under head with partial threading for clearance-hole applications
• Alloy steel construction meets ASTM A574 high-strength socket cap screw requirements
• Black oxide finish provides mild corrosion resistance and a low-reflectance surface
• 0.25-inch hex drive compatible with standard Allen keys and hex bit drivers
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard-dimensioned 5/16-24 UNF hex socket cap screw per ASME/ANSI B18.3, suitable for use in any application or fixture specifying that thread size, drive type, and partial-thread configuration in alloy steel.

Installation Notes

Install using a calibrated 0.25-inch hex key or socket bit driver. Verify thread engagement depth and ensure the mating tapped hole is clean and free of debris before installation. Do not over-drive; alloy socket cap screws are susceptible to cam-out damage in the hex socket if an undersized or worn driver is used. Confirm that the fastener grade is compatible with the base material and load requirements of the assembly per applicable mechanical design standards.
