Hillman Fasteners 41510 Self Drilling Screw 8-18x1 75pk

Product Description

The HILLMAN FASTENERS 41510 is a No. 8-18 x 1 inch self drilling screw designed for fastening into light-gauge metal and similar substrates without the need for a pilot hole. Constructed from hardened steel with a zinc finish for corrosion resistance, this screw features a Phillips drive and a pan head profile. Each pack contains 75 screws, making it a practical choice for production work, field repairs, and general trade applications. Licensed electricians, HVAC technicians, plumbers, and general contractors commonly use self drilling screws when securing sheet metal components, enclosures, brackets, and ductwork fittings.

These screws are suited for light commercial and residential installations where metal-to-metal or metal-to-substrate fastening is required. Typical applications include securing sheet metal duct flanges, electrical junction box covers, equipment panels, strut channel fittings, and similar assemblies. The No. 8-18 thread form and 1 inch length are commonly specified for thin-gauge steel up to roughly 14 gauge. The pan head sits flush against the work surface and distributes clamping load without requiring a countersunk hole.

Key Features

• Self drilling point eliminates the need for a separate pilot hole operation
• Hardened steel construction for strength in metal fastening applications
• Zinc finish provides baseline corrosion resistance in dry indoor environments
• Phillips drive compatible with standard No. 2 Phillips bits
• Pan head profile distributes load and seats flat against the work surface
• 75-count pack suitable for volume trade work and service calls

Compatibility

Designed as a standard No. 8-18 x 1 inch self drilling pan head screw for use in light-gauge metal fastening applications typical to HVAC, electrical, plumbing, and general construction trades.

Installation Notes

Self drilling screws are installed with a power drill or screw gun set to the appropriate clutch setting to avoid over-driving and stripping the head. Ensure the substrate material thickness is within the rated capacity of the drill point before driving. Wear appropriate eye protection when driving self drilling fasteners into metal. Follow applicable building and mechanical codes for fastener spacing and load requirements on structural or pressure-bearing assemblies.
