SLB Monster Bolt 12mm x 80mm

$8.85

Specially developed for crux bolts in soft rock which are repeatedly fallen on. The flexing of normal bolts can cause cracking of the rock below the bolt which is unsightly and worrying even though there is unlikely to be any serious loss of strength. These bolts are naturally much stiffer than normal and this cracking much reduced.

Double start grooves for excellent bonding, TIG welded eye and naturally immensely strong.

Eye internal dimensions 20mm wide x 30mm high.

  • Breaking Strain-Over 60kN
  • EN959.
  • AISI 316 (A4) Stainless Steel 12mm or 1/2″ dia. hole.
