The application after drilling of bore hole continues with insertion of
 two types of resin cartridges with different setting times
and installation of bolts is easy to handle even for staff without skill.
After insertion of bolts by spinning in a short break of 10to 15 sec.
follows before the spinning in procedure starts again
for tightening the plate and tensioning the bolts by torsion of SPIN nut.

The nut allows an initial torque for spinning in, afterwards free running for tensioning and at least a protection against overspun of bolt shaft.

The result is a safe, quick and very cost effective system
and installation procedure.

 FiReP® SPINSET® is a set, consisting of the SPIN BOLT,
SPIN NUT and SPIN PLATE for an improved installation procedure
especially in hard coal mines.
The purpose of this FRP system is the accelerated and
pre-tensioned installation of groups of bolts during systamic bolting
for advanced strata support in mine galleries.
