Value Collection 1510MSR 1/4-28 X 5/8 in Round Head Slotted Screw

Product Description

The VALUE COLLECTION 1510MSR is a 1/4-28 unified fine thread machine screw with a round head and slotted drive. Manufactured from steel with a zinc finish, this fastener meets ASME B18.6.3 and SAE J82 dimensional and material standards. The screw measures 5/8 inches in length under the head, making it well suited for shallow-clearance assemblies where precise thread engagement and a low-profile head are required. This fastener ships in a minimum order quantity of 100 pieces, consistent with professional trade purchasing for maintenance, production, or service applications.

This machine screw is used across a wide range of light industrial, HVAC, electrical, and mechanical assembly applications where a 1/4-28 UNF fine-thread fastener is specified. Fine-thread fasteners like this one are commonly selected where vibration resistance and higher tensile strength per diameter are priorities. The round slotted head style is appropriate for panel assemblies, equipment housings, and service covers in both residential and commercial settings. Sold in multiples of 100, this screw is sized for technicians stocking shop supplies or completing field repairs.

Key Features

• 1/4-28 UNF fine thread for strong engagement and vibration resistance
• Round head profile with slotted drive for standard flat-blade installation
• 5/8-inch length under head for shallow-clearance fastening applications
• Steel construction with zinc finish for corrosion resistance in typical indoor environments
• Meets ASME B18.6.3 and SAE J82 fastener standards
• Minimum order quantity of 100 pieces for trade-volume purchasing

Compatibility

Designed as a standard UNF machine screw replacement for any assembly calling for a 1/4-28 round head slotted fastener per ASME B18.6.3 specifications.

Installation Notes

Install using a flat-blade screwdriver sized to the slotted head to avoid cam-out and head damage. Ensure mating threads are clean and free of debris before installation. Do not overtighten, as fine-thread fasteners in steel can be prone to thread stripping if torqued beyond the rated capacity of the mating material. Follow applicable equipment manufacturer specifications for torque requirements.
