Washer stainless steel A4

Screwmaster screws, nuts and washers in many sizes and different surface coatings – for permanently connecting a wide range of building materials. Easy to assemble and disassemble using the tools appropriate to the screw drive type (external hexagon, internal hexagon, slot, cross recess).


Our screws are suitable for indoor and outdoor use without restrictions. All screws comply with the DIN EN ISO 4017 standard (formerly DIN 933). They have no shaft. In contrast to screws with a solid shaft (DIN EN ISO 4014), they have lower shear forces but better elastic flexibility.


The quality of our products is of particular importance to us as a supplier to trade and industry. Our screws and accessories are therefore subject to constant quality controls. The screw strength is tested, among other things. Our screws have strength class 8.8. This corresponds to a very high quality class and guarantees the strength of the screws. The number before the decimal point provides information about the tensile strength. It corresponds to 1/100 tensile strength in N/mm². A screw with the designation 8.8 can therefore be pulled with 800 N/mm² before it breaks. The number after the decimal point provides information about the yield strength. It indicates the force required to permanently deform the screw by pulling.


If you have any questions about our products, our customer service will be happy to help you.
