Castle Nuts  Manufacturers, Traders, Suppliers

More than 50,000 products. DV-supported stock-keeping. Special parts produced on order.
Our portfolio is already vast with its more than 50,000 standard fasteners- good to know that our online catalogue and our employees‘ know-how keep the overview. But since norms cannot meet all requirements, our programme of products goes beyond DIN data sheets and factory recommendations: special productions according to drawings- from the special type of screws to the plate bending part- complete our offer. We have our own innovations in our programme of products as well. One of our specialties are magnetic plug systems.
They collect the abrasion in gearbox cases or serve as a specially constructed fuel level plunger in wind power stations. In addition we have been involved in further developments of suspension arrangements in the field of mining and tunnel construction. Besides we offer extended screws for which there was a special annex to the DIN norms for the open line construction. A cleverly devised and software-supported stock-keeping and assignment sale make sure that our products are also delivered to you as soon as possible and in a perfectly compiled manner.

High-quality stainless steel fasteners
and efficient C-parts management.Lederer has been one of the leading suppliers of stainless steel fasteners for over 50 years and offers more than 20,000 different items directly from stock:

• Screws, nuts, washers , springs, rings, bolts ...
• made of stainless steel, steel and non-ferrous metals
• Standard and standard parts
• DIN, EN, ISO, L(ederer) and other standards
• Special parts and special materials
• Industry assortments for solar and railroad

At the same time, more and more customers are relying on process-optimized procurement
and C-parts management with Lederer. This provides customers with the following advantages, among others:

• Process cost reduction up to 50%
• Permanent availability and guaranteed quality
• Reduced capital commitment through inventory reduction
• Process-optimized logistics, e.g. Kanban, consignment, etc.

In this respect, Lederer is large enough to also implement sophisticated solutions, e.g. on neutral marketplaces such as Mercateo and NexMart or in corporate solutions such as click2procure from SIEMENS.
At the same time, Lederer is still small enough to react flexibly to market requirements and to implement customer wishes quickly and unbureaucratically. For example, the provision of article and price data in BMEcat and similar structures or the connection to the customer's ERP system via EDI is everyday practice for Lederer.
