Primary Uses & Applications
- Marine & Offshore: Securing panels, instruments, and guards on boats and platforms where salt spray and corrosion are constant challenges.
- Food & Beverage Processing: Mounting components on machinery that requires frequent wash-downs with corrosive cleaners and must meet hygiene standards.
- Medical & Laboratory Equipment: Used in devices where corrosion resistance, cleanability, and reliable performance are non-negotiable.
- Chemical Industry: Applications with exposure to chemical vapors or splashes where component alignment is also needed.
- Outdoor & Architectural: Securing fittings and panels on outdoor structures or in humid environments.
How to Use
- Galling Prevention: Apply a stainless-steel specific anti-seize compound to the threads only before installation to prevent galling (thread cold-welding).
- Insertion: Insert the smooth shoulder through the clearance hole in the top component. Ensure the hole is clean and deburred.
- Driving: Use a high-quality PH2 bit to avoid cam-out. Drive the screw at a moderate, steady speed to minimize heat and friction.
- Tightening: Tighten until the spring is appropriately compressed and the assembly is secure. The shoulder guides the screw and prevents side load on the threads.
- Final Check: Ensure the assembly moves as intended (floats/pivots) without binding. The spring should compensate for thermal expansion and vibration.
