nVent CADDY SMS8 Self-Tapping Self-Drilling Wafer Head Screw, Electrogalvanized Steel

nVent CADDY SMS8 Self-Tapping Self-Drilling Wafer Head Screw, Electrogalvanized Steel

The nVent CADDY SMS8 is a #8 x 1/2-Inch self-tapping, self-drilling wafer head screw built from electrogalvanized steel for reliable metal-to-metal fastening on electrical and construction jobs. Its self-drilling tip bores through light-gauge steel without a pre-drilled pilot hole, while the self-tapping threads cut a clean, tight-holding thread as the fastener drives home. The low-profile wafer head seats flush for a clean, finished appearance on brackets, boxes, and metal framing. Supplied in a box of 1000, the SMS8 gives electrical contractors, panel shops, and installers a ready supply of corrosion-resistant fasteners sized for consistent, repeatable fastening across large installation runs.

Key Features

• Screw Size: #8 x 1/2-Inch, sized for precise fastening into light-gauge metal, sheet steel, and thin structural members.
• Durable Construction: Electrogalvanized steel body resists corrosion, helping the fastener hold up in everyday electrical and construction environments.
• Self-Drilling Tip: Drills its own pilot hole on contact, eliminating a separate drilling step and speeding up installation on the job.
• Self-Tapping Threads: Cuts clean, secure threads directly into metal for a tight, vibration-resistant hold that stays put.
• Wafer Head Design: Low-profile, wide-bearing head sits flush against the mounting surface for a finished appearance and even load distribution.
• Bulk Packaging: Sold in a box of 1000, keeping job sites, panel shops, and maintenance trucks stocked for high-volume installation work.
