Threading Inserts
Free-running helical inserts are precision-formed from cold-rolled, diamond-shaped stainless steel wire to provide smooth, non-locking internal threads. Their flexible helical structure radially adapts to the tapped hole, ensuring uniform load distribution across all engaged threads and increasing pull-out strength. Lacking prevailing torque features, they allow for unimpeded fastener installation and removal. They are extensively used in aerospace, electronics, and automotive sectors to reinforce threads in soft alloys like aluminum and magnesium.
Our free running inserts are available in a range of sizes, materials, and standards. Contact us for a detailed specifications sheet and competitive bulk pricing.
