SIOUX TOOLS INDUSTRIAL CATALOG | DRILLSASSEMBLYClutch Selection GuideClutch Selection GuideType Of JobTorque Control1. Free-Running - Sudden Stop Excellent for all sizescrews.AdjustableGood for all size screws.Close torque control isnot required.Clutch PerformanceDirect/Stall DriveGood for large or mediumnuts or cap screws only.Positive ClutchFair for all size screwswhere close torqueaccuracy is not required.Turns easily until screw head or nut seats against a solidstop. Resistance then builds up suddenly.2. Soft Pull-Up Excellent for all sizescrews.Turns easily until screw head or nut seats, then resistancebuilds up gradually through one or more turns as resilientmaterial compressed.Good for most screws.Close torque control isnot required.Slow on large screws withlong pull-up.Good for large andmedium size scews.Must be adjusted to runrather slowly for smallscrews.Good for small to mediumsize screws.Requires considerableoperator pressure onlarge screws.3. Self-Tapping in Thick Material Excellent for all sizescrews.Increasing heavy resistance through entire travel untilscrew head seats. Then either (A) gradual, or (B) suddenfinal build-up resistance.Not suitable if tappingtorque exceeds strippingtorque.Good for most screws.With proper operatortechnique, can be usedwhere tapping torqueexceeds stripping torque.Slow on large screws.Not recommended unlessstripping torque isconsiderably higher thantapping torque.Good for most sizescrews wherestripping torque isconsiderably higher thantapping torque.Excellent in non-uniformor misaligned material.4. Sheet Metal Screws Good for all size screws.Resistance increases rapidly at first, then eases slightly.At the end, it usually builds up suddenly when screwhead seats.Not suitable if tappingtorque exceeds strippingtorque.Good for most screws.With proper operatortechnique, can be usedwhere tapping torqueexceeds stripping torque.Not recommended unlessstripping torque isconsiderably higher thantapping torque.Good for all size screwswhere stripping torque isconsiderably higher thantapping torque.Excellent when sheetsare frequently misaligned.5. Lock Nuts Excellent for all sizescrews.Good for most screws.Close torque control isnot required.Good for large andmedium screws.Must be adjusted to runrather slowly for smallscrews.Fair for all size screws.Starts with heavy resistance that last through entire traveluntil screw or nut seats. Then either (A) gradual, or (B)sudden further build-up resistance.6. Wood Screws Fair for all size screws. Good for all size screws. Excellent for large andmedium screws.Excellent for all sizescrews.Must be adjusted to runrather slowly for smallscrews.Starts with small resistance that steadily increasesthrough entire travel with additional resistance as screwhead seats.SAFETY PRECAUTION: Read and follow all safety and operating instructions.WARNING: Face & eye protection must be worn while operating power tools, per ANSI B186.131
