CNC precision screws for automation machinery
,stainless steel CNC screws with RoHS compliance
,CNC screw replacements with 0.01 precision
This CNC precision M5 screw replacement accessory set serves as dedicated replacement fitting parts for outdoor sports equipment and 3C electronic devices. It is integrally formed via full-process CNC precision turning, specially developed for old equipment maintenance, module upgrading and transmission component replacement.
The complete assembly consists of a threaded shank body, matching threads, positioning steps and mounting joint structures. It is directly compatible with various automatic linear transmission equipment, displacement adjustment modules and tooling positioning mechanisms. Supported by high-precision closed-loop CNC machining, we strictly control thread accuracy, outer diameter concentricity and overall dimensional consistency throughout production. It perfectly replaces original factory parts to realize zero-tolerance equipment refitting and greatly cut equipment operation, maintenance and replacement costs.
All matching threads undergo full inspection before delivery in strict compliance with metric standard thread profiles and pitch parameters. The go gauge can be fully screwed in smoothly while the penetration limit of the no-go gauge meets specifications.
During replacement installation, threads achieve full and precise meshing to eliminate assembly jamming, thread locking and operating clearance. It matches original standard mounting positions perfectly without secondary trimming.
Adopting one-time clamping composite machining, key parameters including shank outer diameter, step thickness, overall length, thread pitch diameter and concentricity are tightly controlled. Products from the same batch feature highly unified tolerance ranges.
Different from conventionally machined replacement parts, this product has no dimensional deviation, eccentricity, damaged threads or burrs. After refitting, the equipment's displacement accuracy, transmission accuracy and repetitive positioning accuracy remain consistent with original factory standards.
Refined deburring and surface finishing are implemented after machining. No flash, burrs or sharp edges exist on the shank, thread start/end sections, step corners and mounting end faces.
The sleek, delicate surface avoids scratches on equipment bushings, seals and bearing matching surfaces, enabling smooth assembly without jamming. It reduces friction resistance during high-speed reciprocating transmission, effectively lowering operating noise and mechanical abrasion.
- Maintenance & Replacement of Automatic Linear Modules: Suitable for replacing worn screws on servo displacement modules, stepping transmission mechanisms and linear sliding tables.
- Upgrade & Modification of Tooling Positioning Equipment: Used for replacing screw assemblies of non-standard tooling, positioning jigs and adjusting mechanisms.
- Parts Replacement for Small CNC & Conveying Equipment: Applicable to auxiliary transmission structures of small CNC machines, limit assemblies for automatic conveying equipment and precision adjusting devices.
SITUO Hardware specializes in customized CNC machining of screw replacement assemblies for automation equipment. We replicate and customize shank length, thread specifications, step dimensions, positioning structures and mounting outlines one-to-one according to different brand equipment, drawings of old parts and on-site assembly dimensions.
Multi-material customization covering stainless steel, carbon steel, aluminum alloy and brass is offered to fit light-load, heavy-load, humid, oily and other automatic working conditions. Supported by a full-process dimensional inspection system and 100% thread gauge testing, we steadily supply high-compatibility, zero-error, high-precision and burr-free replacement parts.
We have introduced advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines) to better serve our customers' needs. Our maximum processing outer diameter is 60mm, and the minimum control tolerance is 0.001mm.
