Overview
Socket bolt - a bolt of different lengths with a reduced hexagonal head and a partial thread (the thread is longer than in DIN 610). This is a fastening element used to create a reliable connection, the design of which is characterized by a long threaded stud. The bolt is distinguished from other fasteners by the presence of a hexagonal head, a small or large metric thread. Used with a washer and/or nut, and a wrench or socket wrench for installation.
Strength class GOST 7817-70
The GOST 7817-70 bolt strength class is the maximum applied force at which the bolt begins to break. GOST 7817-70 bolts are manufactured in strength class 10.9.
High-strength GOST 7817-70 should be bought only from verified suppliers. It is made of alloy steel and such bolts are used for responsible projects where, in addition to high loads and static loads, the DIN 609 bolt is subjected to constant vibration. Such bolts will be especially relevant in bridge construction, instrument construction, as well as in structures located near objects subject to vibration.
Fastening group GOST 7817-70
High-strength bolts are made only from high-strength steel and belong to the High-strength fastener group.
Materials for the manufacture of bolts GOST 7817-70
High strength bolts are made from only high strength structural alloy steel. The high strength class 10.9 allows the use of bolts in highly loaded connections.
Scope of use of GOST 7817-70 bolts
The GOST 7817-70 bolt is used to connect and fasten parts, structures in construction and mechanical engineering for installation in a precisely machined landing hole without a gap.
