Proper selection of a fastener from the standpoint of its mechanical strength and conditions, in which it is expected to work, are decisive factors in designing bolted junctions.
HERTZ fasteners are fixtures that provide excellent and permanent bond on parts of machines, devices, and framework constructions. Made in compliance with DIN, ISO, PN quality standards, and laboratory-controlled for their mechanical strength, they guarantee the highest quality of workmanship.

Depending on the particular fasteners' planned working environment, various types of steel, copper, brass, and titanium are used in their production, whereas their external coating is made in several basic variants:

• * Galvanising - standard finish,
  * Hot dip galvanising (tZn),
  * Phosphate coating (Znph),
  * Stainless, acid resistant steel (A1, A2, A4),
  * Natural metal colour.

Our HERTZ fasteners are packed by weight.
Depending on workmanship standards, HERTZ fasteners are manufactured in accordance to several mechanical strength classes, i.e.: 4.8, 5.6, 5.8, 8.8, 10.9, 12.9.

Our HERTZ products offer comprises: screws, head screws, nuts, sheet metal screws, and washers.
