About EWG Edelstahlschraubenfabrik Winterberg
EWG Edelstahlschraubenfabrik Winterberg GmbH manufactures rust-free and acid-resistant screws and fastening elements: stud bolts, threaded fittings, threaded pins, threaded rods, set screws, anchor rods, dowels, weld studs and weld-on ends – with inch, fine and trapezoidal threads for the national and international market. In addition to series production, custom designs are produced to customer specifications. The portfolio is complemented by surface treatments such as pickling, passivation, blackening, electrochemical blackening as well as dry lubricant and locking coatings (Gleitmo, DF 911, Adcoat 61/7409, Tuflok), plus degreasing, laser processing, surface hardening, welding and contract work (rolling, milling, drilling, cutting, cutting to length). Materials are stainless steel, acid-resistant steel and steel. Thanks to an extensive warehouse and stockpiling of raw materials, the company enables short delivery times. Customers are private customers, businesses, dealers and wholesalers, in particular from mechanical and plant engineering. The company is located in Wuppertal in North Rhine-Westphalia.

Materials & Processes
Stainless steel / rust-free
Base material for stud bolts, threaded parts and fastening elements with corrosion protection requirements.
Acid-resistant steel
For applications with increased chemical corrosion requirements.
Steel
Material used, among other things, for blackening, surface hardening and weld studs.
Pickling / passivation
Chemical removal of oxide and scale layers as well as formation of a corrosion-resistant layer.
Gleitmo, DF 911, Adcoat and Tuflok coating
Dry lubricant, corrosion protection and anti-loosening coatings on threaded parts.
Blackening / electrochemical blackening
Creation of a black oxide layer or surface as corrosion protection.
Surface hardening
Increase in wear resistance and service life of the material surface.
Contract work: rolling, milling, drilling, cutting, cutting to length
Metalworking to customer specification, also for raw material.
