Frequently Asked Questions

Q: What types of fasteners are used in HVAC and MRO applications?

Common fasteners include bolts, screws, nuts, washers, anchors, and rivets. HVAC applications use sheet metal screws, self-drilling screws, machine screws, and hex bolts. MRO applications span a wide range from structural bolts to precision machine screws.

Q: What is the difference between a self-tapping and a self-drilling screw?

Self-tapping screws cut threads into a pre-drilled pilot hole. Self-drilling screws (TEK screws) have a drill-point tip that drills its own hole and cuts threads in a single operation. Self-drilling screws are commonly used in sheet metal and light structural applications.

Q: What material grades are available for structural fasteners?

Common grades include SAE Grade 2, Grade 5, and Grade 8 for inch fasteners; Class 8.8, 10.9, and 12.9 for metric fasteners. Higher grades offer greater tensile and proof load strength. Stainless steel (18-8, 316) fasteners are used for corrosion-resistant applications.

Q: How do I request bulk fastener sourcing?
