Finserts provide strong metal threads for wood, composition board and thermoplastics such as nylon, polystyrene, cellulose acetate and cycolac.

By distributing stress over a greater surface area, firm permanent fastening is ensured. The fins give higher holding strength in softer materials.

Available with one, two or three fins for varying material thickness, Finserts prevent splintering, splitting and thread pullout.
 
1. Drill a hole using size chart in table.

2. Press Finsert
into place.
3. Insert expands/locks as fastener is threaded into place.
