Cup Point Set Screws Material Options

South Coast Fasteners stocks cup point set screws in the following material types, each selected for strength, corrosion resistant, or specialized wear performance.

Alloy Steel

South Coast Fasteners stocks cup point set screws in alloy steel for strong performance under high-torque conditions. Known for its strength and resilience, alloy steel is a staple for mechanical and industrial assemblies where dependable fastening is required. These screws hold up well in environments that demand both strength and wear resistant.

Alloy Steel Through Hardened

For applications that require uniform strength throughout the fastener, we offer through hardened alloy steel cup point set screws. This treatment process enhances overall toughness and ensures the entire screw, not just the surface, can withstand repeated torque and pressure without deforming or cracking.

Case Hardened Steel

Our case hardened cup point set screws are heat-treated to create a tough outer shell while preserving a more ductile core. This combination is good for situations where surface durability and internal flexibility are both needed, providing excellent wear resistant without compromising structural integrity.

Stainless Steel 18-8

South Coast Fasteners stocks cup point set screws in stainless steel 18-8 for customers who need a dependable balance of corrosion resistant and mechanical performance. Often used in general-purpose applications, 18-8 provides protection against rust in environments such as light manufacturing, outdoor installations, and equipment assembly.

Stainless Steel 316

For tough environments involving marine exposure, chemical processing, or frequent washdowns, we stock cup point set screws in stainless steel 316. This premium-grade material offers strong corrosion resistance compared to 18-8 for long-lasting performance even in aggressive or high-moisture conditions.

Cup Point Set Screws Available Finishes

Black Oxide

Cup point set screws are available with a black oxide finish for improved lubricity and a sleek appearance. This finish provides mild corrosion protection and is commonly used in indoor or controlled environments where visual uniformity and reduced glare are important.

Plain

For projects that involve secondary coatings, welding, or further treatments, South Coast Fasteners also offers cup point set screws with a plain finish. This uncoated option allows for full customization or integration into manufacturing processes without added surface interference.
