Product Description

The M5x20 machine screws, classified as Metric M5x20 fasteners, are precision-engineered DIN 912 M5x20 bolts designed for high-strength assembly across automotive, industrial machinery, and electronics. These hexagonal socket head screws feature a 5 mm diameter and 20 mm shaft length, conforming to DIN 912 standards for uniform thread geometry and ISO 4762 dimensional compliance. Manufactured from grade 8.8 steel or A2 stainless steel, they deliver tensile strengths up to 800 MPa with zinc-plated or natural finishes for corrosion resistance. Suitable for environments ranging from -30°C to 120°C, these fasteners require 5 mm hex keys for installation and maintain secure connections under vibrations. Key advantages include compact design for tight spaces and precise torque transmission up to 8 Nm, though over-tightening risks thread deformation. Their standardized metric threading ensures compatibility with M5 nuts and threaded inserts across mechanical systems requiring reliable, reusable fastening solutions.
