Value Collection R52000336 Machine Screw 1/4-20

Product Description

The VALUE COLLECTION R52000336 is a 1/4-20 x 1.5-inch round head slotted machine screw manufactured from brass. This fastener meets ASME B18.6.3 dimensional standards, making it a reliable choice for applications requiring precise, standardized thread geometry and head dimensions. The slotted drive accepts a flat-blade screwdriver for installation and removal. Brass construction provides corrosion resistance and is well suited to environments where steel fasteners would corrode or where non-magnetic and non-sparking properties are required. Length is measured under the head, at 1.5 inches.

This screw is commonly used in electrical enclosures, plumbing fixtures, marine hardware, HVAC equipment panels, and general mechanical assemblies where brass is specified for compatibility or corrosion resistance. The 1/4-20 Unified National Coarse thread engages standard 1/4-20 tapped holes or nuts. Typical applications include panel fastening, terminal block mounting, and general equipment assembly across residential, commercial, and light industrial settings. Sold individually per package; minimum order quantity is 10 units.

Key Features

• Brass construction provides corrosion resistance and non-magnetic properties
• Round head profile with slotted drive for flat-blade screwdriver installation
• 1/4-20 Unified National Coarse thread for wide hardware compatibility
• 1.5-inch length measured under head per ASME B18.6.3 standard
• No washer included; fits standard 1/4-20 tapped holes and nuts

Compatibility

Designed as a standard 1/4-20 x 1.5-inch replacement or new-installation fastener for any application requiring an ASME B18.6.3-compliant round head slotted machine screw in brass.

Installation Notes

Install using a flat-blade screwdriver sized to the slotted head. Avoid over-torquing brass fasteners, as brass is softer than steel and the head or threads can strip under excessive force. Ensure the mating tapped hole or nut is clean and free of debris before installation. For threaded-hole applications, verify thread engagement depth meets design requirements before final assembly.
