Key Features
- Wide truss washer head provides a broad bearing surface for sheet material.
- Zinc plating provides a protective surface for general indoor and dry-environment use. Cut edges and installation wear can reduce protection.
- Drilling point and threads are designed to form a fastening path in compatible sheet material without a separate tapping operation.
Common Applications
Commonly used for compatible sheet-metal framing, brackets, HVAC ductwork, enclosures, light fabrication, repairs, and metal-to-metal or metal-to-wood fastening after fit has been confirmed.
FAQ
Do these always install without a pilot hole?
No. Performance depends on material hardness, thickness, point geometry, tool speed, and applied pressure. Test on scrap material before production installation.
Can I use them in structural connections?
Do not assume a structural rating. Use an engineered fastener and installation specification when load, safety, or code compliance matters.
Which driver do I need?
Use the correctly sized Phillips bit shown in the product specifications. A worn or incorrect driver can damage the head.
Can they be used outdoors?
Zinc plating provides a protective surface for general indoor and dry-environment use. Cut edges and installation wear can reduce protection.
