Double Fin .375 Long
Finserts prevent splintering, splitting and thread pullout.
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.
1. Drill a .328 hole.(21/64)
2. Press Finsert into place.
3. Insert expands/locks as fastener is threaded into place.
