Flange Lock Nuts at Wholesale Prices – Customize, Global Shipping

FastenMetal Ltd specializes in produce various types fasteners include Flange Lock Nuts, dedicated to delivering high reliability anti-loosening fastening solutions for the automotive, construction, and heavy machinery industries. Our products feature serrated flange faces or nylon inserts, effectively preventing loosening caused by vibration. They are ideal for engine assemblies, bridge anchoring, and wind turbine towers under high-load conditions.

We offer custom manufacturing based on customer drawings, with material options including carbon steel (Q355B), stainless steel (304/316L), and alloy steel (42CrMo). Sizes range from M6 to M200, with a maximum outer diameter of 200 mm.

Thanks to high-precision stamping equipment and multi-directional forging techniques, we achieve a flange flatness tolerance of ≤0.05 mm and tensile strengths exceeding 800 MPa.

Production strictly follows ISO 9001 quality management standards and complies with DIN 6923 / EN 1661. Every batch undergoes torque coefficient testing (0.11–0.15), magnetic particle inspection, and hardness testing (HRC 28–35) across 12 key quality control steps.

Our flange lock nuts are trusted by OEMs, infrastructure projects, and industrial equipment manufacturers in over 30 countries. We guarantee global delivery within 15 days of order confirmation, with rush orders shipped in as fast as 7 days.

2.High Strength Bolts

When regular bolts don’t meet strength requirements, we can produce bolts with strength grades up to Grade 12.9 for your requirements.

3.Custom Shapes and Sizes

We manufacture fasteners in special shapes, lengths, and diameters according to specific applications—fully customized according to your drawings.

In addition to fasteners, we offer custom stamping and metal fabrication services. We have 12 punching machines and press machines for large sheet metal forming and bending, we can handle part thicknesses up to 6mm.

In many of these cases, the customer’s engineering department will provide us CAD drawings and tell us the materials,strength grade they need. We produce samples for customers approval before bulk production.
