Hillman Fasteners 41508 Self Drilling Screw 75 Pack

Product Description

The HILLMAN FASTENERS 41508 is a No. 8-18 x 3/4 inch pan head self drilling screw designed for fast, reliable fastening without the need for a pilot hole. The hardened steel construction with zinc finish provides corrosion resistance suitable for general mechanical and sheet metal applications. Each box contains 75 screws with a Phillips drive, making them a practical choice for HVAC techs, electricians, and sheet metal workers who need a dependable fastener on the job. The self drilling point cuts through material cleanly, reducing installation time on repetitive tasks.

These self drilling screws are well suited for light-gauge sheet metal work, ductwork fabrication, electrical enclosure assembly, and general trade construction tasks. The pan head profile distributes load across the material surface, which is preferred when working with thin panels or covers. The zinc finish offers a baseline level of corrosion resistance for indoor and protected outdoor installations. Sold in a 75-count pack, this SKU is appropriate for both service vans and shop stock where moderate quantities of No. 8 self drilling screws are routinely consumed.

Key Features

• Self drilling point eliminates need for a pre-drilled pilot hole
• No. 8-18 thread size suitable for light-gauge sheet metal fastening
• Hardened steel construction for durability under torque
• Zinc finish provides corrosion resistance for indoor and protected applications
• Phillips pan head drive for fast installation with standard bit drivers
• 75-count pack reduces restocking frequency on active job sites

Compatibility

Designed as a general-purpose No. 8-18 self drilling screw for light-gauge sheet metal, ductwork, and similar trade applications where a pan head Phillips fastener is specified.

Installation Notes

Self drilling screws are typically installed with a power drill or impact driver set to a controlled torque to avoid stripping the Phillips recess or overdriving the fastener. Confirm material thickness is within the rated capacity of a No. 8 self drilling point before use. When fastening electrical enclosures or HVAC components, follow applicable NEC or equipment manufacturer guidelines for fastener type and spacing. Avoid applying excessive torque, which can damage the pan head seat or compromise the connection.
