A receiver block having a first cylindrical bore formed therein through which a stud is fed axially in a downward direction to the collet is also provided. A second bore is formed in the block and has an internal cross-section substantially T-shaped to accommodate a headed stud fed therethrough in a direction normal to the stud axis. The second bore is directed downwardly to intersect with the first bore to form an angle in the range of 0.5 degree to 5 degrees.</p> |
