PN 82408 Countersunk head bolt with projection (whisker)

   PN 82408 is a countersunk head bolt with a projection (whisker). The peculiarity of this bolt is its countersunk head, the absence of a slot and a whisker, which, when it crashes into a wooden surface, does not allow it to twist when tightened. A special whisker prevents the bolt from loosening under the influence of vibration. In cases where it is necessary to connect parts made of wood and metal, the head of the bolt with the whisker is covered with softer material.

Strength class PN 82408

     The strength class of the PN 82408 bolt is the maximum applied force at which the bolt begins to fracture. PN 82408 bolts are available in strength classes 4.6 and 10.9. From strength class 8.8, the bolt is considered high-strength. High-strength PN 82408 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 PN 82408 bolt is subjected to constant vibration.

Fastening group PN 82408

     The PN 82408 bolts are made of high-strength steel and belong to the high-strength fastener group.

Materials used to manufacture PN 82408 bolts

     PN 82408 bolts are made of steel of strength classes 10.9 and 4.6.  The high strength class of 10.9 allows the bolts to be used for highly loaded connections.

Application range of bolts PN 82408

     The application areas for PN 82408 bolts are mainly in the furniture industry, although they are sometimes used in construction and instrumentation. Due to the fact that the bolt has a flat head end that does not contain any elements capable of transmitting torque, the option of unscrewing it from the front side is completely excluded.
