Sheet Metal Tools
HVAC Sheet Metal Tools & Duct Fabrication Tools
We help HVAC contractors and sheet metal workers source aviation snips, duct crimpers, hand seamers, S-clips, drive clips, and sheet metal fabrication tools. Availability may vary by supplier, stock status, and product type.
What This Category Includes
Sheet metal tools are used for duct fabrication, modification, and installation in HVAC systems. This category covers hand tools and accessories for cutting, forming, and connecting sheet metal ductwork in the field.
Aviation Snips
Left-cut, right-cut, and straight-cut snips for cutting sheet metal ductwork. Color-coded handles for quick identification.
Duct Crimpers
Crimping tools for creating male-end crimps on round duct sections for slip-fit connections.
Hand Seamers
Folding and bending tools for creating duct flanges, S-clips, and sheet metal seams.
S-Clips & Drive Clips
Duct connection hardware for joining rectangular duct sections. S-cleats and drive cleats for field duct assembly.
Duct Stretchers
Tools for pulling and aligning duct sections during installation.
Sheet Metal Screws & Fasteners
Self-tapping screws and fasteners for duct assembly and equipment mounting.
Frequently Asked Questions
Q: What sheet metal tools do HVAC technicians use?
HVAC sheet metal work requires aviation snips (left, right, and straight cut), hand seamers, duct crimpers, S-clips and drive clips, sheet metal screws, and duct stretchers. Larger fabrication shops use power shears, brakes, and rollers.
Q: What is the difference between left-cut and right-cut aviation snips?
Left-cut snips (red handles) cut curves to the left; right-cut snips (green handles) cut curves to the right; straight-cut snips (yellow handles) cut straight lines. HVAC technicians typically carry all three for duct fabrication and modification work.
Q: What are S-clips and drive clips used for?
S-clips (S-cleats) and drive clips (drive cleats) are used to connect sections of rectangular sheet metal ductwork. S-clips connect two duct sections end-to-end; drive clips are hammered into the S-clip channel to lock the connection. They are used with duct flanges for field-fabricated duct connections.
Q: What gauge sheet metal is used for HVAC ductwork?
Residential ductwork is typically fabricated from 26-gauge or 28-gauge galvanized steel. Commercial ductwork uses heavier gauges (22–24 gauge) per SMACNA standards. Gauge selection depends on duct size, static pressure class, and applicable standards.
