IBO Bolt and Accessories
Coupler
The FATE Engineering Coupler joins IBO Bolts for safe and flexible installation in long anchoring applications.
About the product
Coupler
The sleeve is one of the key accessories used in FATE Engineering's IBO Bolt system. It connects bolts to each other, allowing for the creation of anchors of the desired length and enabling safe installation at depths that cannot be reached with a single drill.
Thanks to its hollow structure, it prevents the passage of debris and water during drilling. It also ensures a smooth grouting process after drilling is completed. The use of couplings increases flexibility during installation, making it convenient for various tunneling and mining applications. The sleeves are manufactured from high-strength steel and guarantee durability for long-term use.
Applications
Providing connections for long IBO bolt installations
Extending support systems on tunnel ceilings and side surfaces
Anchoring applications in deep ground and rock
Safe and rapid installation in challenging tunnel and mining projects
Features
Achieves the required length by connecting bolts
Made of high-strength steel
Proper performance during drilling and grouting
Available in various diameters and lengths
Fully compatible with IBO bolt systems
FATE Engineering Couplers are a critical connection element that enables the safe and flexible application of the IBO bolt system and can be used with confidence in modern tunneling and mining projects.

Tunnel
Self-Drilling Anchor (SDA)
A hollow, continuously threaded steel anchor system for loose, weathered and collapsing ground that combines drilling, anchoring and grouting in a single operation. Fitted with a drill bit, the bar advances into the ground acting as the drill rod, and remains in place as support once installation is complete. There is no need to insert a bolt into a pre-drilled hole, even where the hole collapses. Cement grout pumped through the bar’s central channel exits through openings in the drill bit, filling the space around the anchor and transferring load between the ground and the anchor. Depending on the method, grouting can be carried out during or after drilling. Bars are joined with couplers to reach the required length, and the anchor head is completed with a plate and nut. Used in tunnel and mine support, slope stabilisation and ground improvement, the bar type, length and drill bit type are selected according to ground conditions and project requirements.

Tunnel
Button Bit
A drill bit used in top hammer drilling for tunnel and mine excavation and for drilling rock bolt holes. Tungsten carbide buttons set into a heat-treated steel body transfer impact energy to the rock and break it. The bit rotates slightly after each blow, so the buttons strike a fresh point on the rock and advance the hole. Flushing holes and channels help clear the cuttings from the hole. Spherical or ballistic button geometry and face design are selected according to rock strength, abrasiveness and fracturing. Produced in a range of diameters with R32, T38 and T45 thread connections; the bit is matched to the hole diameter and drill string.

Tunnel
Cross Bit
Four-wing cross bit with tungsten carbide inserts, giving straight holes and steady penetration in fractured, medium-hard rock. Continuous cutting edges sweep the hole bottom without gaps, keeping the bit on line through fractures. The central port delivers water, air or grout to clear cuttings. On self-drilling anchors (SDA) it is fitted to the bar tip and remains in the hole as a sacrificial bit. In very hard, abrasive rock a button bit is preferred, and in clay or loose ground a clay bit.

Tunnel
Nut
Hex nut for self-drilling anchors (SDA) that locks the plate to the bar and transfers load into it, rated to match the ultimate load of the bar. Its spherical seat, used with a dome plate, keeps the load on axis when the anchor is installed at an angle. Made for R32 to R51 threads in the same plant as the bar and coupler.

Tunnel
PCD Button Bit
Button bit with ballistic (pointed) tungsten carbide buttons, giving a higher penetration rate than spherical buttons in medium-hard, low-abrasive rock. The pointed profile penetrates deeper and concentrates impact energy on a smaller area. Side flushing grooves clear cuttings quickly. In very hard, abrasive rock, where ballistic buttons wear faster, a spherical button bit is preferred. Used for tunnel face drilling, rock bolt holes and self-drilling anchors (SDA).
-
Tunnel
Bearing Plate
Domed bearing plate that spreads anchor load over the rock or shotcrete surface, rated to match the ultimate load of the bar. The pressed dome stiffens the plate. Used with a spherical nut, it keeps the load on axis when the anchor is installed at an angle. Flattening of the dome under overload gives a visible warning on site. Compatible with self-drilling anchors (SDA) and SN rock bolts, made in the same plant as the bar, nut and coupler.

Centraliser
The FATE Engineering Centraliser keeps IBO Bolts centred during drilling and grouting for safe and efficient anchoring.
