Overview
An ISO 8676 full-thread bolt is a fastener consisting of a hexagonal head and a stud with a fine pitch metric thread along its entire length.
Strength class DIN 961
The strength class of a bolt according to ISO 8676 is the maximum applied force that causes the bolt to fracture. DIN 961 bolts are manufactured in strength classes from 8.8 to 10.9. From strength class 8.8, the bolt is considered high-strength. High-strength DIN 961 should be purchased only from trusted suppliers. It is made of alloy steel and such bolts are used for critical projects where, in addition to high loads and static loads, the DIN 961 bolt is subjected to constant vibration. Such bolts will be especially relevant in bridge construction, instrumentation, and in structures that are located near objects subject to vibration.
Fastening group ISO 8676
Depending on the material of manufacture, the hexagonal head bolt is divided into different fastening groups:
- High-strength fasteners
- Stainless steel fasteners
Materials for the manufacture of ISO 8676 bolts
ISO 8676 is available in the following materials:
- Steel, which can optionally be coated with plain and plate zinc
- Stainless steel (A2, A4) does not need to be coated
Areas of application for ISO 8676 bolts
The ISO 8676 bolt is used to connect and fasten parts and structures in construction and engineering.
