Butterfly Screw Metric Wing Bolt Stainless Steel

Butterfly Screw Metric Wing Bolt Stainless Steel Hand Twist Screws Fasteners 304 
The butterfly screw is also known as a wing screw. Wing screw has a wing-like projection from the head of the screw, ideal for thumb and forefinger leverage in turning. Ensures rapid assembly and disassembly using only your hand.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal’s internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present.

Both 304 and 316 stainless steel (as well as other 300-series grades) use nickel to maintain an austenitic composition at lower temperatures. Austenitic steels ensure a versatile balance of strength, workability, and corrosion resistance, making them ideal for outdoor architectural and landscape applications. The benefits of stainless steel include a long service life that will retain an attractive, clean finish with low maintenance cost. It also maintains a high value if and when equipment and parts need to be decommissioned.

In addition to producing Bolts, Hongchuang Hardware can also provide nuts,Washer and Pins,
