The bolt of GOST 1485-84 consists of a cylindrical threaded rod, a square head and a cylindrical guide pin. The assembly unit with the GOST 1485-84 bolt can be additionally equipped with a washer. The square head transmits increased tightening forces for a secure connection in assemblies subject to dynamic loads. The guide pin is an additional positioning element.
Strength class GOST 1485-84
The strength class of a bolt according to GOST 1485-84 is the maximum applied force at which the bolt begins to fracture. Bolts of GOST 1485-84 are manufactured in strength classes from 8.8 to 10.9. From strength class 8.8, a bolt is considered high-strength. High-strength GOST 1485-84 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, GOST 1485-84 bolts are 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 of GOST 1485-84
Bolts of GOST 1485-84 are made only of high-strength steel and belong to the high-strength fasteners group.
Materials for the manufacture of GOST 1485-84 bolts
GOST 1485-84 is made of high-strength structural alloy steel. The high strength class of 8.8 and 10.9 allows the bolts to be used in highly loaded connections.
