Treated screws meet challenging requirements

Treated screws meet challenging requirements
Specially treated and coated screws have been introduced into the latest edition of Rino Industries precision engineered components catalogue. These screws have been variously treated or coated and offer many advantages as a result, the company states.

Raydent treated socket head cap screws offer excellent resistance against corrosion, chemicals and abrasions. They have excellent lubricity which is helps to prevent screw burnouts and biting. Spectral reflectivity is below 1.5 percent making them ideal for use with optics machinery and tools which necessitate reflection prevention. They may be used in rough and medium vacuums, in a clean room, or with FPD and semiconductor production equipment and devices. 

Socket head cap screws with Molybedenum Disulfide coating are ideal for preventing problems that occur during construction and for analysis of machinery, tools and devices. Again, excellent resistance against corrosion and abrasions as well as lubricity preventing screw burnouts and biting is standard.

Teflon coated socket head cap screws feature excellent resistance against heat and chemicals, which means they can be used in chemical resistant applications such as FPD, semiconductor production equipment, PCB etching devices, metallic surface treatment equipment and chemical plants. They will prevent screw burnouts and seizing as they have excellent lubricity. Sizes range from M3 up to M10 threads as standard. In addition, Rino offers gold coatings which provide virtually the same properties as Teflon, with the additions of resistance to acids and electrical conductivity.

Socket head cap screws with a unique alloy plating that has excellent antibacterial, antifungal and anti-algae characteristics, making the screws ideal for use in food processing and medical related machinery. The antibacterial property used is over ten times faster than traditional antibacterial treatments. Even in dark environments, the antibacterial effectiveness continues for long periods of time. An electroless nickel plating is available on socket head cap screws offering a strength classification of 12.9, which makes them ideal for machinery or tools that cannot use rust preventative oil. Sizes range from M3 to M5 as standard.

Trivalent chromate treated socket head cap screws are the last in this range offering a reduced environmental impact as they are hexavlent chromium-free, RoHS directive compliant and have a strength classification of 10.9.
