Heat Treated Ball Head Blind Hole Nut

Product introduction

The ball head blind hole nut is a high-end fastener that integrates precision structural design and practical functions. Its unique design combines a ball end and a blind hole thread structure. It is specially developed for precision application scenarios that require hidden connections, beautiful assembly and special angle adjustment. This product belongs to the typical processing category of customized special-shaped fasteners and plays an irreplaceable role in aerospace, precision instruments, high-end electronics and medical equipment industries. As one of the representative products of non-standard parts made in China, blind ball nuts demonstrate my country’s technological accumulation and manufacturing strength in the field of precision fasteners. As a professional Wenzhou non-standard parts factory, we have established a complete blind ball nut manufacturing system based on more than 20 years of experience in focusing on the production of precision fasteners. From material science to molding technology, from heat treatment technology to surface treatment, every link is carefully designed and strictly controlled to ensure that every product can meet customers' precise requirements. Especially in the construction of cold heading non-standard parts factory, we introduced German multi-station cold heading molding equipment, combined with independently developed mold manufacturing technology, to achieve high-precision, high-volume and consistent production of ball head blind hole nuts.

 

Product design and features

Spherical head design: Using precise spherical geometric structure, the radius tolerance is controlled at ±0.02mm, and the surface finish is above Ra0.4 to ensure smooth assembly. Optional full or partial spherical design can meet different installation needs. Blind hole thread design:

The internal thread adopts precision tapping technology, and the thread accuracy reaches 6H level. The depth of the blind hole can be customized, up to 3 times the diameter. The bottom is designed with an undercut groove to ensure the integrity of the thread.

Diversity of material selection: stainless steel series: 304, 316, 316L, 440C, etc., alloy steel series: SCM435, 35CrMo, 42CrMo, etc. Special materials: titanium alloy, copper alloy, high temperature alloy, etc. Surface treatment options: nickel plating, zinc plating, chromium plating, anodizing, passivation treatment, DLC coating, Teflon coating.

 

Manufacturing process features: Multi-station cold heading forming: 8-station cold heading machine is used in the cold heading non-standard parts factory, with a one-time forming rate of more than 95%.
