Standard and custom metal & hardware products, manufactured to your drawings. All items below can be made in your required size, material, finish and packing.
Can't see exactly what you need? Most of our business is custom — send a drawing or sample and we will quote it.
Hex head bolts (DIN 931), hexagon socket head cap bolts in Grade 8.8 / 10.9 / 12.9, black-oxide and zinc-plated screws, flat-head Torx and countersunk machine screws, DIN 444 eye bolts, shoulder screws, T-head bolts, hardened dowel pins, U-bolts, hex flange & lock nuts, flat & spring washers and standoff spacers — plus fully custom non-standard fasteners. Threads follow DIN, ANSI, JIS, ISO or your drawing.
Precision components machined and cut to drawing — CNC turned and milled shafts, pins, bushings, sleeves and spacers, aluminium / brass lead-screw shafts, laser-cut and stamped metal plates, and hydraulic & pneumatic fittings. Prototype to volume, with repeatable tight tolerance.
Stamped and formed sheet-metal parts for hardware, electrical and mechanical assemblies — brackets, clips, terminals, covers and shims. Progressive-die and deep-drawing tooling is designed and built in-house, which keeps unit cost and lead time down for both prototypes and volume runs.
Injection-molded and machined plastic parts that complete your assembly — hex nylon standoff spacers, POM / PE / nylon / ABS / PVC bushings, protective caps and sleeves, knobs and custom profiles, made to sample or drawing.
The most frequently requested combinations. Other grades and finishes are available on request.
