Value Collection R52000891 No. 8 Self Drilling Screw 5/8 in

Product Description

The VALUE COLLECTION R52000891 is a No. 8 self-drilling screw designed for fast, reliable fastening in light steel and sheet metal applications. The hex washer head provides a broad bearing surface and a built-in seal, while the hex drive allows high torque transfer with standard hex bit drivers. The 2-point drill tip eliminates pre-drilling by cutting its own pilot hole as the screw is driven. Constructed from Grade 1016/1024 steel with a zinc-plated finish, this screw offers corrosion resistance suitable for general indoor and light-duty outdoor mechanical assemblies. Sold in multiples of 100 per order.

This screw is widely used in HVAC ductwork fabrication, electrical enclosure assembly, light-gauge metal framing, and equipment panel fastening. The 5/8-inch length under head suits thin-material applications where thread engagement in 24-gauge to 16-gauge sheet metal is required. It is a standard choice for sheet metal technicians, HVAC installers, and electricians who need a self-tapping, self-drilling fastener that seats flush and fast without a separate drill step.

Key Features

• No. 8 diameter with a 2-point drill tip for self-drilling into light-gauge steel without pre-drilling
• Hex washer head delivers a wide bearing surface and helps seal the fastening point
• Hex drive accepts standard 5/16-inch hex bit drivers and nut drivers
• Grade 1016/1024 steel construction meets AISI 1016, ASME B18.6.3, and SAE J78 standards
• Zinc-plated finish provides corrosion resistance for general mechanical and HVAC applications
• 5/8-inch length under head is well-suited for thin sheet metal and light structural panels

Compatibility

Designed as a standard No. 8 self-drilling screw for use in light-gauge steel sheet metal, HVAC duct systems, electrical enclosures, and similar thin-material assemblies where a 2-point drill tip and hex washer head configuration are specified.

Installation Notes

Installation is performed by sheet metal technicians, HVAC installers, and electricians using a standard hex-drive bit or nut driver in a variable-speed drill or screw gun. Power down or de-energize any electrical enclosure before fastening into or near live panels. Do not overdrive: once the washer head seats against the material surface, stop driving to avoid stripping the hole or deforming the base material. Follow applicable installation standards such as SMACNA guidelines for duct fabrication or the NEC for electrical enclosure work.
