Special Chromate protective plating eliminatesrust and corrosion.11THE MORE THEY VIBRATE — THE TIGHTER THEY LOCKCAMSRIDGESWhen the bolt contracts, the inclinedplanes of the cams causethe nut or capscrew to rotate backto its original position. This createsa fastening system that is vibrationproof and meets military specifi -When a bolt elongates due tovibration or shock, the nut orcapscrew starts to rotate loose.The Vi-LOC system prevents thissince the cam rise angle is greaterthan the lead angle of the thread. Asone piece of the Vi-LOC attemptsto rotate with the nut or capscrew,the preload is actually increased,forcing the assembly back to a tightfi tting unit.The Vi-LOC principle calls for twowasher-shaped pieces that haveinclined cams on one side and aseries of ridges on the other. Whenthe inclined cams are mated andset-up as shown in the diagram, onewasher seizes to the joint materialand the other washer to the nut orcapscrew.cations. The Vi-LOC fasteningsystem may be loosened byexerting approximately 50% moretorque than required for tightening.VI-LOCK WASHERS• USE ONLYIN PAIRS• SELF-MATING• RIDGES ONOUTSIDERESISTS:• VIBRATION• LOST HOLDING POWER• SLIPPAGE• WEAR• EQUIPMENT BREAKDOWNSIZE INSIDE DIAMETER OUTSIDE DIAMETER PART3/16 (5mm) .203" .401" U61001/4 (6mm) .262" .495" U61015/16 (8mm) .326" .628" U61023/8 (10mm) .409" .705" T61037/16 (11mm) .450" .880" T61041/2 (12mm) .510" 1.005" R61059/16 (14mm) .572" 1.128" O61065/8 (16mm) .651" 1.247" O61073/4 (20mm) .820" 1.381" O61107/8 (22mm) .883" 1.470" L61111" (25mm) 1.015" 1.626" L6112100112 FOR MORE INFORMATION ON OUR PRODUCTS OR SYSTEMS, CALL 1-800-BUY-BOLT11.5
