The 18-8 Stainless Steel Hex Head Cap Screw is a popular fastener known for its strength, durability, and corrosion resistance. Composed primarily of 18% chromium and 8% nickel, it is part of the 300 series of stainless steels, which are widely recognized for their excellent performance in various environments. This material blend offers a balance of strength, toughness, and resistance to oxidation, making it suitable for use in demanding conditions, including high moisture or corrosive environments.
Specifications:
18-8 Stainless Steel Hex Head Cap Screws typically feature a hexagonal-shaped head, which allows for easy tightening using a wrench or socket. These screws are available in various sizes, including different thread pitches, lengths, and diameters, offering flexibility for many different applications. They are commonly manufactured with a fine or coarse thread design, depending on the specific requirements. In terms of mechanical properties, 18-8 stainless steel offers a tensile strength of approximately 70,000 to 100,000 psi, ensuring that the screw is strong enough to withstand heavy loads. Additionally, the screws are resistant to rust, corrosion, and oxidation, even in high-temperature environments up to about 800°F (427°C).
Users:
The 18-8 Stainless Steel Hex Head Cap Screw is widely used by engineers, contractors, and maintenance professionals in industries that require reliable, corrosion-resistant fasteners. It is favored by manufacturers of machinery, equipment, and automotive parts. It is also commonly used in construction, plumbing, and HVAC applications, where durability and resistance to harsh conditions are essential. Additionally, this type of fastener is often used in the food and pharmaceutical industries, where hygiene and resistance to corrosion are critical.
Applications:
18-8 Stainless Steel Hex Head Cap Screws are versatile and can be applied in a wide range of industries, including automotive, aerospace, marine, and construction. They are ideal for use in applications where exposure to moisture, chemicals, or extreme temperatures could lead to the degradation of other materials. Common applications include securing engine parts, machinery components, structural assemblies, and outdoor equipment. Their corrosion resistance makes them perfect for use in coastal or humid environments where other metals might fail.
