Thread System
NOVOCON Rock Bolts are produced under strict quality control in two types of thread profiles:
1. Standard Thread: conforms to ISO, UNC or DIN standards. Rolled thread is known as the stronger thread than conventional cut one.
2. Thread Bar: is manufactured under Thai Industrial Standard (TIS). This special type of thread is the special coarse thread. Its big advantage is that customers can cut and connect it anywhere just by a coupler and a nut.
Various Sizes
NOVOCON Rock Bolts are available in size Ø16 mm, 20 mm, 25 mm, 28 mm, 32 mm, and 40 mm. The full standard lengths are 10 and 12 meters. The longer length can be obtained by using mechanical connector (coupler).
