Product Details

This fastener is distinguished by several key engineering features. The screw is manufactured from high-strength carbon steel to meet the Grade 8.8 property class, giving it a high tensile strength suitable for load-bearing connections. The “rolling tapping” or thread-forming design is a critical feature; unlike thread-cutting screws that create metal chips (swarf), these screws cold-form the threads into the material. This creates a zero-clearance, work-hardened fit that is exceptionally resistant to loosening from vibration and provides higher pull-out strength.

The screw features a versatile pan head, which offers a low profile and a large bearing surface for good clamping force. It is driven by a standard Phillips cross recess for easy installation with common tools. A durable galvanized zinc coating provides excellent protection against corrosion. While the primary product is the Grade 8.8 carbon steel version, we also offer these screws in stainless steel and with a wide variety of head styles to meet any project requirement.

General Specifications:

Product Features

Our screws are manufactured to deliver superior performance and flexibility, offering several key advantages:

• High-Strength Performance: Manufactured to Grade 8.8 specifications, providing the high tensile strength required for demanding and structural applications.
• Superior Fastening Integrity: The thread-forming design creates a tight, vibration-proof connection with greater holding power than conventional tapping screws.
• Clean, Chipless Assembly: By displacing material instead of cutting it, these screws eliminate the risk of metal swarf contaminating sensitive assemblies like electronics or hydraulic systems.
• Unmatched Flexibility (No MOQ): With no minimum order quantity, we can support everything from prototyping and small repairs to full-scale production runs.
• Extensive Customization: A wide variety of head styles, materials (including stainless steel), and finishes are available to create the perfect fastener for your needs.
• Certified Quality: Our manufacturing process is certified to ISO 9001:2015 standards, ensuring consistent quality and reliability.

Product Applications

The unique combination of strength and thread-forming capability makes these screws ideal for:

• Automotive Assembly: Fastening components to metal frames and chassis where vibration resistance is critical.
• Sheet Metal Fabrication: Providing strong, reliable threads in sheet metal panels and enclosures.
• Heavy Machinery and Equipment: Assembling structural components, guards, and mounting brackets.
• Industrial Racking and Shelving: Creating strong, durable connections in metal framework.
• Appliance Manufacturing: Used in the assembly of major appliances where a robust and lasting connection is needed.
