Bosta – Self-Tapping Screw for STP Counter Current System 4.2 × 16 mm

This is a genuine Bosta replacement self-tapping screw, sized 4.2 × 16 mm, designed specifically as a spare part for the Bosta Counter Current System Type STP. It provides the secure mechanical fastening needed to keep covers, panels, and internal components firmly in place on the STP unit.

Compatibilitate

This screw is an OEM spare part for the Bosta Counter Current System Type STP series. The STP is a pool jet-stream system used to generate adjustable counterflow for swimming training, featuring a front cover panel housing the nozzle, suction port, and pneumatic switch — all of which rely on correctly specified fasteners for safe, leak-free assembly. Always verify your STP model and part requirements before ordering.

De ce autenticitatea contează

Using the correct genuine Bosta fastener ensures the dimensional fit, thread profile, and material specification exactly match the original factory assembly. An incorrectly sized or non-OEM screw risks stripping threads in the housing, incomplete sealing, or panel instability — all of which can compromise the performance and safety of your counter current system.

Instalare

Self-tapping screws of this type cut their own thread on first installation, so they should be driven carefully at the correct torque to avoid over-tightening and cracking the surrounding housing material. If replacing an existing screw, inspect the receiving hole for damage before fitting. Professional installation or the guidance of a qualified pool technician is recommended.
