Product Introduction

The Little Pan Head Six Lobe Self-Drilling Screw is designed for metal fastening applications requiring a low-profile head with positive drive engagement and corrosion resistance. The little pan head configuration provides a flat underside with a lower profile than standard pan heads, offering accurate clamping force distribution while maintaining a compact appearance suitable for confined spaces and aesthetic applications. The six-lobe drive enables positive torque transmission with reduced cam-out risk during installation, providing reliable engagement with standard six-lobe tools. The self-drilling point drills and taps threads simultaneously, eliminating pilot hole requirements and reducing assembly time. Manufactured from SUS410 stainless steel with Dacromet surface treatment, this screw provides hardness for metal fastening with high corrosion resistance for demanding environments. The 4.8-24 thread specification with 45mm length offers engagement for structural connections and heavy-duty metal assemblies.

This little pan head six-lobe self-drilling screw is deployed in metal fastening applications requiring a low-profile head with positive drive engagement and corrosion resistance. Applications include confined space assemblies where standard pan heads may not fit, aesthetic metal connections where appearance is important, equipment enclosures, automotive components, industrial machinery, structural steel connections, outdoor metal assemblies, and heavy-duty fabrications where the little pan head provides a compact profile, the six-lobe drive enables positive engagement, and the Dacromet coating ensures long-term corrosion protection.

Common Questions and Solutions

What are the advantages of the little pan head design?

The little pan head provides a lower profile than standard pan heads while maintaining accurate clamping force distribution. This compact design is suitable for confined spaces where standard head profiles cannot be accommodated and offers a clean appearance for visible applications.

What is the recommended six-lobe tool size for this screw?

Select a six-lobe driver that matches the head size specified for the 4.8-24 thread. Refer to the product specification for the exact six-lobe size required for installation.

What material thickness can the 4.8-24*45 screw accommodate?

The 4.8-24 specification with 45mm length provides engagement for structural connections and heavy-duty metal assemblies. The actual maximum material thickness depends on the drill point length and substrate hardness. Consult the technical datasheet for specific thickness recommendations.

What is the Dacromet coating and what are its benefits?

Dacromet is a water-based zinc flake coating that provides high corrosion resistance with extended salt spray protection. It offers an environmentally friendly alternative to conventional plating processes and is suitable for outdoor and industrial applications requiring long-term corrosion protection.

Is this screw suitable for outdoor applications?

Yes. The SUS410 stainless steel material combined with Dacromet coating provides corrosion resistance for outdoor applications. The low-profile head also helps prevent snagging in exposed installations.

What is the recommended installation speed for this screw?

Install at controlled speeds to avoid overheating the drill point. Excessive speed may reduce drill point life and cause thread stripping. Use torque-controlled drivers to prevent over-tightening when the little pan head contacts the workpiece surface.

Installation Considerations

Select the correct six-lobe driver size that matches the screw head recess to ensure positive engagement and prevent drive wear during installation.

Use torque-controlled installation tools to prevent over-driving. The little pan head should seat against the workpiece surface without damaging the head or surrounding material.

Apply appropriate spindle speed based on material hardness; excessive speed may reduce drill point life and cause thermal damage to the Dacromet coating.

Ensure perpendicular alignment between screw axis and workpiece surface to prevent drill point deflection and ensure clean hole formation.

The Dacromet coating provides corrosion resistance. Handle screws with clean gloves to maintain coating integrity and prevent contamination that could affect corrosion performance.

For applications requiring specific torque values, consult the technical datasheet for recommended installation parameters.
