Figs. 59-62. — Round bars raajf be held singh' or in multiple with one- or 

 two-piece formed plugs and clamped either with screw or nut and washer. 

 Clamping plugs may be reamed in place for accurate contact with round 

 pieces. 



Fig. 63. — Soft flexible wire that 

 withstands twisting offers an effi- 

 cient retention of either slotted 

 or drilled screws. This shows a 

 method used extensively in auto- 

 mobile rear-axle design.
