Flange Nut ISO 7043

Product Description

The metric Nylon Insert Flange is a hex drive nut and washer combination. This product combines the best attributes of both common hex nylon insert and flange type locknuts and requires sufficient thickness to accommodate wrenching height and nylon collar height. It is common to find product with blue nylon rings, designating the part as metric.


The flange makes the Nylon Insert Flange locknut ideal when assembling components that consist of thin materials, slots or non-precision oversize holes. Mating part must extend at least one thread past the flange nut top surface to assure locking element engagement. The flange will typically require more torque to produce a clamp load than non-flange nuts.
