Value Collection R52001049 1/4-20 X 1 in Machine Screw

Product Description

The VALUE COLLECTION R52001049 is a 1/4-20 x 1 inch round head machine screw designed for general-purpose fastening in mechanical, HVAC, electrical, and light structural assemblies. The screw features a slotted Phillips drive, allowing installation with either a flat-blade or Phillips screwdriver. It is manufactured from steel with a zinc-plated finish that provides basic corrosion resistance in dry indoor environments. The thread size is 1/4-20 UNC with a length under head of 1 inch, conforming to ASME B18.6.3 and SAE J82 dimensional standards. This fastener is sold individually per package with a minimum order quantity of 100 pieces.

This screw is suited for light-duty fastening applications across residential and commercial trades. Typical uses include panel mounting, equipment assembly, and securing components to sheet metal or tapped holes. The round head profile sits above the surface, making it appropriate where a low-profile or flush finish is not required. Electricians, HVAC technicians, and general mechanical contractors routinely use this fastener size in control panels, equipment enclosures, and field-fabricated brackets.

Key Features

• 1/4-20 UNC thread for compatibility with standard tapped holes and nuts
• Round head with slotted Phillips drive accepts flat-blade or Phillips screwdrivers
• Zinc-plated steel finish for basic corrosion resistance in dry indoor environments
• Length under head of 1 inch per ASME B18.6.3 dimensional standard
• Meets SAE J82 material grade requirements for steel machine screws

Compatibility

Designed as a standard 1/4-20 UNC machine screw for use in any application requiring ASME B18.6.3 compliant fasteners with a round head slotted Phillips drive and 1 inch length under head.

Installation Notes

Install with a Phillips or flat-blade screwdriver sized for a 1/4-20 head. Ensure the mating thread or nut is clean and free of debris before fastening. Do not overtighten into tapped sheet metal, as the zinc plating and base material are not rated for high-torque structural applications. Follow applicable codes and equipment manufacturer guidelines when securing electrical enclosures or HVAC components.
