Bolted Couplers must be correctly installed to ensure that the full working capacity can be achieved. The coupler should be complete with the correct number of bolts and the two serrated strip saddles in place inside the coupler. For correct installation, all the bolts must be tightened until the heads shear off. * Bolted Couplers are easy to install and achieve failure loads higher than 775% of the characteristic yield strength of grade 500 reinforcing bar. Neither bar end preparation to form threads, nor bar rotation are required. Bolted couplers can also be used tojoin imperial, plain round or deformed reinforcing bars.
