Stainless Steel Fastener Assembly with Slotted Expansion Anchor Screw and Threaded Shank

Slotted expansion anchor screws produced to deliver controlled expansion and consistent fit. For each run we tightly control diameter tolerance, fit class, and thread standard so assemblies stay reliable over time. Send a toleranced drawing when you need tight control over thread engagement and expansion range. When your slotted expansion anchor screw must seat consistently, we adjust surface finish to suit the mating material. At our Dongtai production plant—operating under an IATF 16949, ISO 9001, and RC 14001-certified QMS standard—we manufacture stainless steel fasteners for automotive and industrial applications. In operation since 1991, the facility provides passivation and shot blasting in-house, serving aerospace, railway, and shipbuilding applications. Costs and schedules reflect batch size, inspection scope, and finishing operations.
