Installation Procedure

1. Clean mating surfaces and threads of both the screw and the receiving component to remove any debris or contaminants. 2. Apply a suitable thread lubricant or anti-seize compound if specified by the application requirements. 3. Thread the M18x52mm Hex Head Cap Screw into the designated fastener hole, ensuring it engages smoothly and is not cross-threaded. 4. Tighten the screw to the manufacturer's specified torque value using a calibrated torque wrench, ensuring proper tension and secure fastening without over-stressing the component.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during tightening, leading to thread stripping or component damage.Always use a calibrated torque wrench and adhere to the specified torque values for the application to prevent over-tightening.
Not cleaning mating surfaces, which can lead to uneven load distribution and premature fastener failure.Thoroughly clean all threads and mating surfaces before installation to ensure proper seating and optimal performance.
Using incompatible thread lubricants or anti-seize compounds that can compromise the fastener's integrity or the assembly's performance.Consult the application engineering specifications for recommended lubricants or anti-seize compounds compatible with Titanium Grade 5.

Common Applications
