18-8 Stainless Steel Narrow Cheese Head Slotted Screws, JX-21JG425-M3-12-SS&CNC stainless steel machined parts, catering equipment, baking ovens, microwave ovens, range hoods manufacturing application solutions, surface treatment passivation

More corrosion resistant than steel, and almost as strong, these 18-8 stainless steel screws have a narrower head than pan head screws to fit into tight spaces. They’re often used in electrical panels and next to flanges and raised surfaces in humid, damp, and washdown environments, but will corrode if exposed to salt water or chemicals. A deep slot gives you more driving power and keeps the screwdriver from slipping. Length is measured from under the head.

Passivated screws are finished with an extra layer of rust protection.

Screws with an extended tip, sometimes called a full dog point, fit into a hole or slot to keep parts such as pulleys and gears aligned. Use these screws in place of dowel pins; their threads clamp your parts down and keep them from rotating.

NAS 721 screws meet National Aerospace Standards. ISO 1207 (formerly DIN 84), DIN 920, and DIN 922 screws meet international standards for fastener dimensions.

Stainless steel screws are screws made using stainless steel wire. Used in the production of fasteners mainly austenitic stainless steel, refers to the stainless steel is also austenitic stainless steel. The performance characteristics of stainless steel screws are specifically the following four points:

1, stainless steel screws are a family of iron alloys, each with a chromium content of more than 12%. Chromium is a corrosion-resistant component, so all stainless steel has strong corrosion resistance. By and large, the higher the content of chromium, the better the corrosion resistance.

2, the use of nickel elements in stainless steel screws fasteners in the process of using stainless steel as a material, once more dependent on the use of nickel elements, but in the case of rising global prices of nickel elements, the price of fasteners has also been greatly affected.

3, stainless steel screws in the fastener use stainless steel as the main material, but also to understand the magnetic properties of stainless steel itself. Stainless steel is generally thought not to be magnetic, but austenitic series of materials after a certain processing process, is possible to appear a certain magnetic, but if you think that magnetic is the standard for determining the quality of stainless steel fasteners is also incorrect.

4, all stainless steel contains iron and chromium in addition to the composition, but also contains carbon. But the content of carbon is very low and is carefully controlled. The reason is that carbon can be combined with chromium to form carbide, making the chromium component of which has a very small effect on the formation of corrosion resistance. Therefore, to achieve the effect of corrosion resistance, when the carbon content increases, the content of chromium should be increased accordingly.
