Saves on Field Complaints

A diversified industrial oem in India produced various hydraulic and pneumatic equipment. In their hydraulic cylinder unit the customer used a competitive threadlocker to lock and seal the zinc plated MS nipple to the cast iron cylinder head. The product they used was a slow curing product and did not perform well in presence of oil traces on the thread surfaces. Customer received frequent field complaints of Nipple loosening and the changes the axis from cylinder head.

Avoids Field Failures and Protects Threads from Corrosion

LTM India is a leading manufacturer of tyre processing machines in India. They used nylock nuts to lock the heavy M16 bolts on the pci machines. However, the ylock nuts loosened due to heavy vibrations and thermal cycling that the tyre machines are subjected to. The bolts at the bottom plates f the machine were not easily accessible for retorquing or inspection and once they lost clamp load hey easily loosened. LTM was receiving frequent customer complaints on this.

Outperforms Expensive Nyloc nuts, Maintains Clamp Loads under Severe Conditions

Nifty Lifts, Australia makes Hydraulic Lifts for forestry, mining and construction use. Base turn table of the lift holds boom & bucket and is subjected to severe vibrations, impacts & shear loads. 16mm structural bolts on the turn table loosened under these conditions. Nifty used nyloc nuts to prevent vibrational loosening of these bolts but even nyloc nuts failed to retain clamp load over long periods. Bolts had to be retorqued frequently; any premature failure can result in accidents.

Use of Loctite® 770 Allows Adhesion on Inactive Surfaces

A leading manufacturer of electric motors, geared motors, torque limiters, variable frequency drives, soft starters and more in Australia used PP capacitor boxes. Customer wanted to lock threaded plastic parts of these capacitor boxes made of Polypropylene. Customer tested competitive, general purpose adhesives but these fail to perform. PP is a low surface energy material and is difficult to bond.

Reduces Field Complaints

A leading manufacturer of small domestic appliances was using star washers to lock the yellow passivated M4 screw of top lid handle of domestic pressure cookers they were making. They had several field complaints of handle loosening over the usage period as the star washer not only failed to retain the clamp load but also was unable to accommodate difference in thermal expansion between dissimilar materials.
