Overview
A cap nut is a nut that covers a threaded part both decoratively and to protect the thread. DIN 917 can be used in places with limited space. This design of the nut allows not only to ensure a reliable connection at the point of attachment of structural elements, but also gives it a more aesthetic appearance. Also, the closed shape of the cap nut performs a protective function, protecting against scratches and cuts that can be inadvertently caused by the protruding edges of the bolt.
Strength class DIN 917
The strength class of a DIN 917 nut is the maximum applied force at which the nut begins to fracture. DIN 917 nuts are made of steel of strength class 6.
DIN 917 fastening group
Depending on the material of manufacture, DIN 917 nuts are divided into groups:
- Stainless steel fasteners
- Brass fasteners
Materials for the manufacture of DIN 917 nuts
DIN 917 nuts are made of the following materials:
- Steel, strength class 6, which can optionally be coated with zinc. Zinc protects against corrosion if the fastener is to be used in aggressive environments.
- Stainless steel of steel grades A2 and A4. Allows the bolts to be used at significant temperature fluctuations and in aggressive and humid environments.
Areas of application for DIN 917 nuts
DIN 917 is used in playgrounds, sports equipment, etc. The purpose of the product is to provide a threaded connection of parts subjected to low loads, with a small protrusion of the threaded part and requirements for the absence of sharp edges.
