Hillman Fasteners 116119 Self-drilling Metal Screws 210ct

Product Description

The HILLMAN FASTENERS 116119 is a 210-count box of 8-18 x 1/2 inch hex washer head self-drilling metal screws designed for fast, reliable fastening in light-gauge metal applications. The self-drilling tip eliminates the need for pre-drilling, allowing direct penetration into metal up to 1/8 inch (11 gauge) without additional setup steps. Each screw features a star drive recess paired with a Pro-Stick bit that resists cam-out and maintains bit engagement throughout the drive cycle. This combination reduces fastener spin-out and speeds up installation in repetitive production or service work.

These screws are suited for HVAC ductwork fabrication, sheet metal enclosures, metal framing, electrical panel work, and general trade applications where metal-to-metal fastening is required. The hex washer head provides a broad bearing surface that resists pull-through on thin metal sheets. The 210-count quantity makes this box practical for ongoing service work or job-site supply. Installers working in HVAC, electrical, or light construction will find this size useful for standard gauge metal assemblies.

Key Features

• Self-drilling tip penetrates metal up to 1/8 inch (11 gauge) without pre-drilling
• Star drive recess with Pro-Stick bit reduces cam-out and improves driving stability
• Hex washer head delivers broad clamping surface on sheet metal
• 8-18 thread form optimized for metal-to-metal fastening
• 210-count box quantity supports production and service workflows

Compatibility

Designed as a general-purpose self-drilling metal screw for light-gauge sheet metal assemblies up to 11 gauge (1/8 inch) in HVAC, electrical, and metal framing applications.

Installation Notes

Installation is performed with a hex-drive or star-drive bit matched to the Pro-Stick specification included with the fastener. No pilot hole is required in metal at or below 11 gauge. Apply consistent axial pressure during driving to maintain bit engagement and prevent cam-out. Always wear appropriate eye protection when driving self-drilling fasteners into metal.
