The GPM C30OD80TK30 Spring Steel 3.0mm Ring Tilted OD:8.0mm, TK:2.5mm Countersink Screws set is supplied as a 20-piece kit of spring steel fasteners intended for high-stress mounting points. Each screw is specified for consistent seating and repeatable mechanical performance in competitive or high-use models.
These countersink screws provide improved resistance to vibration-induced loosening and retain clamping force under dynamic loading. The tilted ring seating geometry ensures reliable contact with countersunk holes while the spring steel material offers high yield recovery to reduce permanent deformation during servicing.
