Description:

Locknuts splicing require neither bar end preparation to form threads nor bar rotation to effect installation.

The bars are supported within the coupler by two serrated saddles. As a series of lock-shear bolts are

tightened to a predetermined torque, they are embedded into the bar. At the same time the saddles bite

into both the bar and the shell of the coupler. Installation is complete when the heads of all of the bolts

are sheared off. The lock-shear bolts on sizes 10mm to 20mm can be tightened using a ratchet wrench.

For larger sizes a nut runner is recommended. Impact tools must not be used. Lock-nuts splicing can be

used to join imperial, plain round or deformed reinforcing bars.

Competitive Advantage:

1. Site assembly with standard impact wrench.

2. No need of bar end preparation

3. Readily available off the shelf.

4. Ideal for concrete-embedded bars, repair and retrofil works, bent bars, etc…

5. Type A splice as per ACI 318 requirements. Complies with BS 8110 and NF A35-020 standards.
