M20 x 2.5mm coarse thread pitch – multiple lengths available
This M20 x 2.5mm hex cap screw is manufactured from Class 8.8 steel with a zinc plated finish for reliable corrosion resistance in general-purpose applications. Class 8.8 is the most widely specified metric bolt grade, delivering approximately 800 MPa tensile strength for structural, mechanical, and equipment assembly across virtually every industry. The hexagonal head provides a positive drive surface for wrenches and sockets, allowing efficient installation and high clamping force. Available in both partial and full thread configurations, these fasteners accommodate a broad range of joint designs. The zinc plating adds a uniform protective barrier against moisture and atmospheric corrosion while maintaining full RoHS compliance.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head FT = Full Thread PT = Partial Thread
