Value Collection 1510MSF 1/4-28 X 5/8 Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 1510MSF is a 1/4-28 flat head slotted machine screw manufactured from steel with a zinc finish. It measures 5/8 inches in overall length and is produced to ASME B18.6.3 and SAE J82 standards. The flat head profile sits flush with or below the mating surface, making it well-suited for applications where a low-profile fastener is required. This screw is installed by electricians, HVAC technicians, plumbers, and general maintenance professionals wherever a standard unified fine-thread fastener is needed in light to medium-duty assemblies.

The 1510MSF is intended for use in metal and equipment assemblies that require a 1/4-28 UNF thread engagement. The fine thread pitch provides stronger thread engagement and better resistance to vibration loosening compared to coarse thread equivalents. Typical applications include electrical panel assembly, equipment enclosures, control box mounting, and general mechanical assemblies in trade and industrial settings. This screw ships in a minimum order quantity of 100 pieces per package.

Key Features

• 1/4-28 UNF fine thread for secure, vibration-resistant engagement
• Flat head profile allows flush or countersunk seating in mating material
• Slotted drive compatible with standard flat-blade screwdrivers
• Steel construction with zinc finish for corrosion resistance in standard indoor environments
• Manufactured to ASME B18.6.3 and SAE J82 dimensional standards
• Overall length of 5/8 inches equals length under head

Compatibility

Designed as an OEM-style replacement or standard fastener for equipment and assemblies requiring a 1/4-28 UNF flat head slotted machine screw per ASME B18.6.3.

Installation Notes

Install using a flat-blade screwdriver sized to the slotted drive. For countersunk applications, ensure the mating material is properly chamfered to the correct angle before seating the flat head flush. Do not overtighten, as doing so can strip the threads or crack countersunk material. Follow applicable mechanical and electrical codes when using fasteners in panel or enclosure assemblies.
