About Nuts, Materials, and Finishes

Zinc-Plated Steel

These inserts have four prongs on the flange to resist twisting in hardwood and softwood. Hammer them into a drilled hole to install. Installed length includes the flange.

Zinc-plated steel inserts are mildly corrosion resistant in wet environments.

Metric Steel Round-Base Weld Nuts

These weld nuts have a smooth base that provides more contact with the mating surface than weld nuts with projections. The base also acts as a flange to distribute the load. A long barrel ensures secure thread engagement.

Zinc-plated steel weld nuts are corrosion resistant in wet environments.

Stainless Steel Adhesive-Mount Nuts

These nuts have excellent resistance to chemicals and salt water. Large holes in the base to allow adhesive to flow through. They’re often molded into plastics and used to add threads to plastic that is too thin to fit a threaded insert.

T-Slotted Framing Fasteners

Screw and nut sets or nuts secure brackets and other accessories to rails.

End-Feed Fasteners

End-feed fasteners slide into the end of the rail to attach components.

Self-aligning fasteners have a ridge that keeps them centered in the T-slot.

Drop-In Fasteners


	Spring-Tab Nut
	Hammer Nut

Drop-in fasteners can be placed directly into the T-slot to attach components—no need to disassemble your existing structure. They consist of a screw and nut.

Spring and spring-tab fasteners hold the nut in place so it won't slide down vertical rails.

Hammer fasteners drop in to the slot and turn into place when the screw is tightened. They're serrated to break the anodized coating on the rail, allowing static to dissipate.
