In the fastener market, external tooth lock washers are valued for their ability to maintain preload under vibration, a property supported by typical Brinell hardness between 120 and 180 HB. Tensile strength generally ranges from 400 to 800 MPa depending on the selected material, providing reliable load transfer in mining, oil‑gas and automotive assemblies. Standard outer‑diameter sizes fall between 5 mm and 30 mm with thicknesses of 0.5‑2 mm, matching most ISO‑compatible bolt groups. Packaging is normally supplied in cartons stacked on pallets, but Milfast can adapt to specific shipping requirements.

The listed minimum order quantity is 1 000 pieces, and the supplier accepts OEM modifications to material, finish or dimensions upon request. Shipping is arranged in cartons or palletised loads, with the buyer responsible for agreeing Incoterms and payment terms directly with the factory. Prospective importers should confirm current lead times and any required certifications before placing an order.
