It transfers load from the unstable exterior to the confined (and much stronger) interior of the rock mass. Srons Engineers are the largest manufacturers, suppliers and exporters of all types of Rock Bolts in India.
R thread self-drilling rock anchor

The coupling offers a flexibility to easily adjust the rod length to the site requirements, it is especially widely used in a confined workspace with limited head room.
T thread self-drilling rock anchor
T type self-drilling rock anchor consist of a hollow threaded (trapezoidal thread) rod with a sacrificial drill bit, plate, nut, and an extension coupling. The coupling offers a flexibility to easily adjust the rod length to the site requirements, it is especially widely used in a confined workspace with limited head room.
Prestressed rock anchor
Prestressed rock anchor consists of a hollow threaded (rope thread) rod with a expansion shell type anchor head, plate, nut, and an extension coupling.

Couplers are used to join various segments of anchor bar together. Simply match the coupler size to the bar diameter and multiple bars can be easily joined together. The coupler thread has a break in the center making it easy to ensure that both the front & back end bar meet in the middle of the coupler.

Adapters are used with anchor bars to allow a larger drill bit to be used with a smaller bar. The anchor bar threads into the inside of the adapter and the drill bit on the outside. This can be a cost saving solution for applications that do not require the strength of larger diameter bars but benefit from a thicker cross section of grout.
