Frequently Asked Questions — Brass Knurling Inserts
To provide a precise quote, please submit your detailed engineering drawings (2D or 3D CAD models), specify the required brass grade, quantity (minimum batch sizes apply), thread specifications, knurling type, and any surface finish requirements.
Yes. As a leading brass inserts exporter from India, we export over 92% of our production to OEM buyers and distributors in the USA, Germany, UK, Canada, UAE, and European industrial hubs, supplying containerized and airfreight B2B shipments.
We manufacture diamond knurled inserts, straight knurling inserts, helical inserts, panel hexagonal inserts, and custom geometries. These can be designed as through-hole or blind-hole inserts for injection molding or press-fit insertion.
Yes. We manufacture RoHS-compliant lead-free brass knurling inserts to satisfy strict environmental and safety regulations in global markets, providing full material test reports with each shipment.
We utilize calibrated GO/NO-GO thread plug gauges, optical profile projectors, and automatic sizing instruments to check concentricity, thread tolerance class, outer diameter consistency, and knurl tooth depth.
Diamond knurling inserts feature a crisscross knurl pattern that provides bi-directional mechanical interlocking. This ensures high torque-out resistance (preventing the insert from rotating when a screw is tightened) and high pull-out resistance (preventing it from being pulled out of the plastic).
