Collection: UNF inserts

Manufactured from austenitic stainless steel wire, inserts provide a high performance internal thread that:

• exceeds the strength of most parent materials
• maintains bolt tension under severe vibration conditions
• is corrosion resistant, preventing adverse seizing and galling
• is wear resistant, virtually eliminating friction-induced thread erosion
• is lightweight without sacrificing thread strength
• withstands temperatures ranging from -200°C to +425°C

UNF inserts will suit a tapped hole to BS3409 and finished thread to BS1580.
