SECURITY LOCKNUT INC. EXPANDS METRIC SIZE RANGE TO INCLUDE M10 - M52

Mundelein, IL - August, 2006 - Responding to increased global demand for metric sizes of its innovative locknut that is capable of maximum holding power and able to be removed and reused many times over, Security Locknut Inc. has developed the product in sizes M10 – M52. Previously offered in select metric sizes only, this unique locknut has found application in mining, material processing, rail, off-road/heavy vehicle and equipment, amusement rides, construction, presses, turbines, and cylinders...applications where shock, vibration, stress, or environmental conditions cause fastener failure or periodic maintenance requires reusability or safety.

With the superior locking performance delivered by its proprietary, elliptical spring steel locking concept, the Security Locknut radially locks onto a bolt or mating shaft making it absolutely vibration and shock proof. Using the Security Locknut eliminates the need for traditional fastening systems like double nuts, serrated fasteners, flex-type or distorted, pin and nylon insert locknuts that fail, time after time or costly, unnecessary processes such as wire-tying or welding. Installation and removal requires no special tools. Only a standard torque wrench or ratchet is all that is needed.

The Security Locknut product is heat-resistant to 750°F (395°C), offered in Coarse and Fine pitch metric sizes compatible with Class 8.8 or Class 10.9 bolts. Heavy and Jam styles are available. American Standard Finished and Heavy Hex pattern sizes in UNC & UNF threads and customs, too.

ELLIPTICAL SPRING STEEL INSERT MAKES LOCKNUT HOLD TIGHT ...AND REUSABLE

The innovative 2-piece construction of a new locknut design makes it capable of maximum holding power, yet allows it to be removed and reused many times. Offered by Security Locknut Inc., this unique locknut has found application in rail, off-road, construction, mining, even presses and amusement rides...critical applications where periodic maintenance requires reusability.

In essence, the insert locks the bolt, while the nut secures the joint. The Security Locknut concept further creates an absolutely vibration-proof fastening system, critical in applications where double nuts, serrated fasteners, distorted and nylon insert locknuts fail, time after time.

These new locknuts feature an elliptical spring steel insert, which is mechanically joined to the nut body in a permanent union. Installation requires only a standard torque wrench or ratchet.

The Security Locknut product is heat-resistant to 750°F (395°C), offered in standard sizes 3/8" - 4" and compatible with Grade 5 or Grade 8 bolts. Full and jam nut styles available with fine or coarse threads. Metric sizes, too.
