Value Collection R52000822 No. 4 Hex Washer Screw

Product Description

The VALUE COLLECTION R52000822 is a No. 4 hex washer head sheet metal screw with a slotted drive, designed for fast, reliable fastening in light-gauge sheet metal and thin material applications. It features a Type AB point for easy thread engagement without a pilot hole in most applications. Manufactured from 1016/1024 grade steel with a zinc finish for basic corrosion resistance, this screw measures 0.25 inches in length under the head. The hex washer head provides a wide bearing surface and is driven with a standard hex driver or slotted screwdriver. Meets ASME B18.6.3, ASME B18.6.4, AISI 1016, and SAE J933 standards.

This screw is suited for residential and light commercial HVAC, electrical enclosure, ductwork, and general sheet metal assembly work. The No. 4 thread size and quarter-inch length make it appropriate for thin-gauge panels, junction box covers, and similar low-profile fastening tasks where thread-cutting into metal is required. Sold in multiples of 100 per order.

Key Features

• No. 4 thread size with Type AB self-tapping point for direct engagement in sheet metal
• Hex washer head provides wide bearing surface and two-way drive compatibility — hex or slotted
• 1016/1024 grade steel construction meets AISI 1016 and SAE J933 material standards
• Zinc finish for basic corrosion protection in indoor applications
• Conforms to ASME B18.6.3 and ASME B18.6.4 dimensional standards
• 0.25-inch length under head suits thin-gauge sheet metal panels and enclosure covers

Compatibility

Designed as a standard No. 4 hex washer head sheet metal screw for use in thin-gauge steel panels, ductwork flanges, electrical enclosures, and similar light-gauge sheet metal assemblies requiring a self-tapping Type AB fastener.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, electricians, and general sheet metal workers using a hex nut driver or slotted screwdriver. Ensure material thickness is appropriate for a No. 4 thread before driving. Do not overtorque — the small thread size is susceptible to strip-out in thin-gauge material. Follow applicable NEC or IFGC enclosure and ductwork fastening requirements for the specific assembly.
