Features of Inch Hand Thumb Screws
Thumb Screw Round Title:
Corrosion Resistance M4 M5 M8 M12 or Custom thumb screw stainless steel color thumb screw
Knob Thumb Screw Thread Introduction:
The core is composed of stainless steel screws and an integrated butterfly screw head, which belongs to the fast installation and quick disassembly standard fasteners, suitable for various equipment and scenarios that require frequent disassembly and assembly and do not require high-strength fastening.
Material:
A2 (304 Stainless Steel): Universal stainless steel, resistant to common atmospheric corrosion, weak acids and bases, with high cost-effectiveness, suitable for conventional industrial, civilian, and office equipment scenarios;
A4 (316 Stainless Steel): Marine grade stainless steel, containing molybdenum element, resistant to seawater, strong corrosion, chemical media, suitable for outdoor, marine, chemical, and medical equipment scenarios;
Customizable 316L Stainless Steel: Low carbon 316 stainless steel with excellent welding performance and resistance to intergranular corrosion, suitable for precision instruments and food machinery.
Thread Size
Metric: M3, M4, M5, M6, M8, M10 (mainstream conventional specifications, suitable for the vast majority of devices);
Imperial: # 4-40, # 6-32, # 8-32, 10-32, 1/4-20 support customization.
Head diameter
Butterfly shaped head diameter: 18mm, 22mm, 25mm, 30mm, 35mm or as per your requirements
Thread Length
Metric standard: 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 30mm; Support non-standard customization: Customize special thread lengths (4mm-100mm optional) according to customer equipment requirements.
Core Production Technology
Precision cold heading forming/Thread rolling: high-precision rolling process/Surface passivation treatment&polishing without burrs.
