Power Tool Manufacturer Reduces Warranty Claims with LOCTITE® Threadlockers

Customer Challenge

A leading power tool manufacturer faced increasing warranty claims on one of its heavy-duty service tools designed for skilled trades and contractors. Engineers traced the problem to a recurring issue: fastener loosening during use, which compromised tool reliability and customer satisfaction.

Henkel Solution

After a detailed review, a LOCTITE® technical sales engineer recommended LOCTITE® 277™ high-strength threadlocker. This solution was selected for two key reasons:

1. Seamless Integration – Easy to apply during assembly, requiring no major process changes.
2. Proven Performance – Delivers superior resistance against shock, vibration, and heavy-duty use.

During assembly, just a drop of LOCTITE® 277™ is applied to the fasteners. Its high viscosity ensures it stays within the thread roots, preventing migration. Once fasteners are inserted and torqued, the liquid cures into a tough thermoset plastic that securely locks the threads in place.

Results

By incorporating LOCTITE® 277™ into the assembly process, the manufacturer eliminated warranty claims related to fastener loosening. The tool now delivers:

• Increased reliability under demanding conditions
• Reduced warranty costs and after-sales service issues
• Enhanced brand reputation among professional contractors

With LOCTITE® 277™, the company restored customer confidence and ensured its tools continue to meet the high-performance expectations of skilled professionals.
