The Cup Point Hexagonal Socket Setscrew applies pressure directly against the piston surface to prevent movement between assembled components. This fastening method allows accurate positioning of rotating parts within mechanical assemblies. Holding parts tightly in place supports consistent alignment and stable operation during rotation and vibration. It enables controlled tightening, allowing for the adjustment of component position during installation or maintenance.Attributes:• Cup point tip creates firm contact with the shaft or component surface.• Hexagonal socket drive enables controlled tightening with an Allen key tool.• Compact headless design allows installation in recessed assemblies.• Thread engagement supports stable holding force during operation cycles.Applications: The Cup Point Hexagonal Socket Setscrew is installed in piston assemblies, holding parts in position and maintaining stable operation during repeated piston movement.
