Hexagon L-Key Wrench: Hardened Zinc-Plated Anti-Slip Precision Tool
Core Product AdvantagesProducts

This screw integrates zinc plating, cross recessed pan head and anti-loosening shoulder design, with precise shoulder step positioning for strict axial spacing control. The zinc-plated surface forms a dense protective layer, delivering reliable rust resistance for humid industrial environments, while the cross recessed pan head ensures easy and stable tool engagement during installation, no slipping or stripping. The anti-loosening structure effectively prevents loosening caused by vibration, maintaining long-term connection stability for mechanical equipment and precision components.
Customization SpecificationsProducts
We support targeted customization of this screw to match diverse application needs, with thread sizes ranging from M1.6 to M18 and lengths 3mm to 120mm. The shoulder diameter and height can be customized according to technical drawings, adapting to non-standard fixture, automotive part and electronic device assembly requirements. All products adopt cold-forging head and rolled thread processes, ensuring solid structure and strong holding power, with 100% dimensional verification via laser measuring tools to meet precise assembly standards.

Material Matching & PerformanceProducts
The base material for this galvanized locknut can be selected from 1018/1045 carbon steel or 304/316 stainless steel. The carbon steel version has a higher tensile strength and is an economical choice suitable for general industrial non-corrosive scenarios; while the stainless steel version has better corrosion resistance and is suitable for outdoor or humid working environments. All galvanized surfaces undergo strict salt spray tests (12 - 150 hours) to ensure they do not rust and maintain stable performance over a long period of use.
