Split Set rock bolts (friction bolts) are manufactured to a highest standard of quality.

Rigid standards of quality are achieved by exhaustive quality control,

testing and inspection procedures. Detailed drawings specify materials, dimensions, and tolerances.

Every Split Set is identified with model number, length, factory, rolling date, and heat lot of the steel.
