Description
Overview:
This Countersunk Screw (M6 x 10 mm) is a genuine Hatz fastener for the 1B40 and 1B50 series engines. It is designed to deliver precise, secure fastening where a flush, snag-free surface is needed, helping keep engine covers and components aligned and secure under vibration. Built from durable materials suited to engine environments, it supports reliable assembly and maintenance tasks without altering clearances around housings or guards. The flat, countersunk head sits level with the mating surface, making it suitable for visible or tight-fitting panels. As an OEM-matched part, it helps maintain factory fit and performance on Hatz single‐cylinder engines, reducing the risk of loosening and wear over time. OEM reference: 50380800.
