Product Description
Custom Mushroom Head Blackened Plastic Nut
Situo Hardware is an original-source custom factory specializing in non-standard mushroom-head blackened plastic nuts, dome-shaped protective plastic cap nuts, and CNC turn-mill composite machined plastic fasteners for equipment assembly.
Product Overview
This series of non-standard mushroom-head blackened plastic nuts is manufactured from engineering plastics including PA66, POM, and ABS. Using CNC turn-mill composite integrated machining, multiple features including mushroom-head arc top surface, hexagon driving surface, internal thread, and step positioning are completed in one clamping setup, eliminating cumulative errors and ensuring thread coaxiality and precision.
Blackening surface treatment provides uniform matte black appearance for decoration, dust-proof, and thread-protection purposes. The rounded domed mushroom-head covers bolt ends after installation for insulation and visual improvement. Full-parameter customization is available for thread size, mushroom-head arc diameter, head height, hexagon across-flat dimension, and step dimension.
Factory Technology & Core Advantages
- Material Selection: High-performance engineering plastics (PA66, POM, ABS) with insulation, vibration-damping, chemical-corrosion resistance, and light weight properties
- Precision Machining: Integrated CNC turn-mill composite machining reduces positional deviation and ensures controlled thread coaxiality, arc profile, and hexagon dimensions
- Protective Design: Mushroom-head domed design provides dust-proof and anti-collision performance while optimizing visual appearance
- Customization Capability: Full-parameter non-standard customization including internal thread specification, mushroom-head dimensions, hexagon width, and step limits
- Surface Treatments: Optional matte blackening, natural-color polishing, and sandblasting with sharp-edge chamfering and deburring
- Quality Control: Comprehensive procedures covering raw-material verification, dimensional inspection, thread testing, and appearance screening
Application Scenarios
- Mushroom-head blackened plastic insulating protective nuts for automation equipment housing assembly
- Domed decorative & protective plastic cap nuts for instrument housings and electric-control modules
- Non-standard turn-mill machined plastic nuts for tooling jigs and testing-equipment assembly
- Dust-shield nuts for thread ends of electromechanical devices and small-size machinery
- Equipment assembly requiring insulation, light-weight property, and sharp-edge elimination
- Non-standard fastening scenarios demanding mushroom-head domed profile and matte-black appearance
Delivery & Service
Complete manufacturing workflow: plastic bar cutting → CNC turn-mill composite integrated machining → tapping → deburring → blackening surface treatment → finished-product inspection. Sampling lead time: 3-5 days. All order volumes accepted with material property reports and dimension inspection reports available.
