8 This advantage can also have adrawback: If a nut inadvertently backs-off abolt, the result might be a minor inconvenienceor a major disaster. Locknuts were developedto overcome this potential Brief History of SPS Self-Locking NutsSPS Technologies started as Standard PressedSteel Co. in 1903. Early on, the companyrealized a need for high quality, dependablefasteners of all types for its manufacturingoperations. None were available in themarketplace, so SPS designed their own uniqueself-locking nuts and developed the machiner yneeded to produce them. This was the origin ofFLEXLOC self-locking HeroWorld War II was the showcase for the FLEXLOC product s first real world, problem-solvingapplication. Army Ordnance specified theself-locking nuts to stop track bolts fromcoming loose on army tanks in the field ofcombat. This dramatic application brought FLEXLOC locknuts to the attention of the boomingaircraft industr y.

9 The product s initial use inthis demanding market was in the design of theBoeing B-29. According to a biography writtenby the founder of SPS, FLEXLOC locknuts wereused extensively in the aircraft. This led toacceptance of the fastener throughout theindustr y. Due to these and later successes, the defenseindustr y sought out SPS for help instandardizing locknut PRODUCTS . To a largeextent, the militar y specification NASM25027for locknuts was written based on the FLEXLOCnut per formance. Today, SPS Technologies FLEXLOC self-lockingnuts are used by the militar y and aerospaceindustries in air frame, space vehicle andmissile assemblies; piston, turbine and rocketengines; as well as ground support ever y major militar y and commercialprogram in production today utilizes SPS self-locking Self-locking nut One-piece, all metal, prevailing torque locknutsFLEXLOC Higher temperature use than non-metallic insert type locknuts Ever y thread carries a portion of the induced load Impact, shock and vibration resistance Elimination of lock wires, lock washers and inserts Locking without seating can be used as stop nuts Easy installation and removal Reusability - To NASM25027 More reliable then plain nuts, lock washers, castellated nuts with cotter pins and jam nuts Identification - SPS stampFor nearly a centur y SPS has been committedto providing PRODUCTS that offer a superior levelof quality and per formance.

Achieving this level of product integrity requiresuncompromising quality assurance. Statisticalmonitoring is an integral part of qualityassurance at SPS.
