Value Collection R52001072 Machine Screw 1/4-20 X 2.5 in

Product Description

The VALUE COLLECTION R52001072 is a 1/4-20 x 2.5-inch round head machine screw designed for general-purpose fastening in metal fabrication, equipment assembly, and maintenance applications. Made from steel with a zinc-plated finish for basic corrosion resistance, this screw accepts both a slotted and Phillips drive, giving installers flexibility in driver selection. It conforms to ASME B18.6.3 and SAE J82 standards, ensuring dimensional consistency and material grade compliance. At Grade J82, it delivers reliable tensile performance suitable for light-to-medium duty mechanical assemblies. Length is measured under the head per standard convention.

This screw is well suited for trade and industrial settings where a standard inch-series coarse-thread fastener is required. Common applications include panel mounting, equipment enclosure assembly, electrical box fabrication, and general mechanical repair. The round head profile provides a low-profile bearing surface without requiring a countersunk or flush mounting surface. The zinc coating offers adequate protection in dry or mildly humid indoor environments. Sold as a single piece with a minimum order quantity of 100 units.

Key Features

• 1/4-20 coarse thread with 2.5-inch length under head for deep fastening reach
• Dual-drive round head accepts both slotted and Phillips drivers
• Steel construction with zinc-plated finish for basic corrosion resistance
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• Grade J82 material for consistent mechanical performance in general assemblies
• No washer — clean bearing surface against the mating part

Compatibility

Designed as a standard inch-series 1/4-20 coarse-thread machine screw compatible with any tapped hole or nut meeting ASME B18.6.3 specifications for that thread size.

Installation Notes

Install with a flat-blade or Phillips screwdriver, or a 1/4-inch hex bit driver for power installation. Ensure the mating tapped hole or nut is clean and free of debris before threading. Do not overtighten — torque to the fastener manufacturer or equipment OEM specification for Grade J82 steel in the applicable joint configuration. Replace any fastener showing signs of thread damage, corrosion, or deformation.
