If sourcing HVAC parts takes too long, breaks your flow, or creates more questions than answers — you’re not alone. Here’s what many HVAC manufacturers tell us they deal with every day:
HVAC assemblies demand more from fasteners than simple strength. Connections must hold ductwork, panels, and enclosures securely, resist vibration, and prevent leaks — all while standing up to temperature swings and outdoor exposure. That’s why we supply solutions with finishes and design features that go beyond basic performance, helping OEMs reduce maintenance and extend system life. Below are some of the most commonly used fasteners in HVAC applications:
Adhesives, sealants, and tapes
Blind Rivets
Cable ties and accessories
Connectors, Terminals & Clips
Copper fittings
Cord grips and protectors
Cushion clamps
Custom fabricated parts
Electrical fittings
Nylon Insert Lock Nuts
Grommets
Hole plugs
Hose clamps
OEM assembly and service kits
PEM self-clinching fasteners
PVC fittings
Rivet nuts
Self-Drilling Screws
Sems Screws
Studs and Threaded Rods
Subassemblies
Tapping Screws (Sheet Metal Screws)
Thread Cutting Screws
Thread Rolling Screws

Choosing the correct pilot hole size for thread-forming screws in thin-gauge sheet metal helps prevent stripped threads, ensures proper engagement, and reduces installation torque. The ideal size depends on both the screw diameter and the material thickness or gauge. In general:
Thinner materials require a slightly smaller pilot hole to create strong threads without distortion.
Harder materials like stainless steel may need a slightly larger hole to reduce driving torque. Not often thought about, but laser cut holes also have a harder edge from the laser, and should have a slightly larger hole.
Aluminum and softer steels allow for tighter pilot holes for maximum thread engagement.
For precise recommendations by screw size, material, and sheet gauge, refer to our Sheet Metal Hole Size Guide — it includes an easy-to-read chart for applications using thread-forming screws.
