Value Collection R52000823 Size 4 Sheet Metal Screw

Product Description

The VALUE COLLECTION R52000823 is a No. 4 round head sheet metal screw designed for fastening light-gauge sheet metal, thin steel, and similar materials in HVAC, electrical, and general sheet metal fabrication work. Constructed from AISI 1016 steel with a zinc plated finish for corrosion resistance, this screw has a length under head of 0.25 inches. It conforms to ASME B18.6.3 and ASME B18.6.4 dimensional standards, making it a reliable choice for applications that require consistent, specification-grade fasteners. Sheet metal mechanics, HVAC installers, and electricians will find this screw suited for everyday panel assembly and enclosure work.

This screw is commonly used in residential and commercial HVAC duct assembly, electrical panel and enclosure fabrication, and general sheet metal joining applications. The round head profile provides a broad bearing surface and is appropriate where a low-profile or pan head is not required. Sold individually but subject to a minimum order quantity of 1000 pieces per order, making this SKU appropriate for contractors and shops purchasing in bulk for ongoing production or service work.

Key Features

• AISI 1016 steel construction for consistent mechanical strength in light fastening applications
• Zinc plated finish provides basic corrosion protection in dry indoor environments
• Round head profile delivers a broad bearing surface on sheet metal
• Meets ASME B18.6.3 and ASME B18.6.4 dimensional standards
• 0.25 inch length under head suits thin-gauge material fastening
• Grade 1016-1024 material specification for consistent hardness and thread performance

Compatibility

Designed as a standard No. 4 round head sheet metal screw for use in light-gauge steel sheet metal assemblies, HVAC ductwork, and electrical enclosures where ASME B18.6.3 and ASME B18.6.4 compliant fasteners are specified.

Installation Notes

Sheet metal screws of this type are installed by licensed sheet metal mechanics, HVAC technicians, and electricians using a manual or powered screwdriver with the appropriate bit. Always ensure the material thickness is compatible with the screw length before driving to avoid stripping or pull-through. Follow applicable codes including SMACNA standards for duct assembly and NEC requirements for electrical enclosure fastening. Pre-drilling a pilot hole is recommended in harder or thicker gauges of steel to prevent material distortion.
