Value Collection R52001334 1/4-20 X 1-1/2 in Machine Screw

Product Description

The VALUE COLLECTION R52001334 is a 1/4-20 x 1-1/2 inch round head machine screw manufactured from steel with a zinc-plated finish. It features a combination slotted and Phillips drive, allowing installation with either a flat-blade or cross-point screwdriver or bit. The length measurement is taken under the head, meaning 1-1/2 inches of thread and shank extend below the bearing surface. Conforming to ASME B18.6.3 and SAE J82 standards, this fastener is suited for general-purpose mechanical assembly across industrial, commercial, and maintenance applications. No washer is integrated into the head design.

This screw is used wherever a 1/4-20 threaded fastener with a low-profile round head is required. Common applications include machine assemblies, electrical enclosures, equipment panels, and structural fixtures where a clean, domed head appearance is acceptable. The zinc plating provides a basic level of corrosion resistance for indoor and light-duty outdoor use. Sold individually per package with a minimum order quantity of 100 pieces, making it appropriate for shop stock, service vehicles, or production line replenishment.

Key Features

• 1/4-20 thread size with 1-1/2 inch length measured under the head
• Combination slotted and Phillips drive accepts flat-blade or cross-point tools
• Round head profile provides a domed appearance with full bearing surface
• Steel construction with zinc-plated finish for corrosion resistance in light-duty environments
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• No washer — clean installation against flat mating surfaces

Compatibility

Designed as a standard 1/4-20 inch-series machine screw for general mechanical assembly applications requiring ASME B18.6.3 conformance.

Installation Notes

Installation is performed by general mechanics, electricians, or maintenance technicians using a 1/4-20 tapped hole or appropriate nut. Verify that the mating thread is clean and free of debris before driving. Use a properly sized slotted or Phillips bit to avoid cam-out and head damage. Do not exceed the torque capacity appropriate for Grade J82 steel fasteners in the relevant joint material.
