Specification: M5.0-3.0*80

Material: SUS410

Surface Treatment: Waxing

Product Introduction

The CSK Six Lobe With Step Type 17 Drywall Screw is a specialized fastener designed for drywall and gypsum board installation requiring flush surface finish with enhanced drive engagement and improved seating. The countersunk head configuration allows the screw to sit level with or below the workpiece surface when used with a corresponding countersink, providing a smooth appearance and eliminating protrusions for finishing. The six-lobe drive enables positive torque transmission with reduced cam-out risk during installation, providing reliable engagement with standard six-lobe tools. The step feature beneath the head provides enhanced seating and alignment in countersunk holes. The Type 17 thread features a specialized buttress profile that reduces driving torque while maintaining pull-out resistance in drywall substrates. Manufactured from SUS410 stainless steel with waxing surface treatment, this screw provides hardness for metal fastening with enhanced lubrication for smooth installation. The M5.0-3.0 thread specification with 80mm length offers extended engagement for multi-layer drywall systems and thick substrate applications.

Common Questions and Solutions

What is the Type 17 thread and what are its benefits?

The Type 17 thread features a specialized buttress profile with a flat driving face and angled back face. This design provides improved engagement in drywall substrates, reducing driving torque during installation while maintaining pull-out resistance and holding power.

What is the function of the step feature under the head?

The step feature provides enhanced seating and alignment when the screw is installed in countersunk holes. The stepped design helps center the screw in the countersink and provides consistent seating depth for improved installation accuracy and finishing.

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

Select a six-lobe driver that matches the head size specified for the M5.0-3.0 thread. Using the correct driver size prevents driver slippage and damage to the drive recess. Refer to the product specification for the exact six-lobe size.

What material thickness can the M5.0-3.0*80 screw accommodate?

The M5.0-3.0 specification with 80mm length provides extended engagement for multi-layer drywall systems and thick substrate applications. The actual maximum thickness depends on the number of drywall layers and substrate depth. Consult the technical datasheet for specific thickness recommendations.

What is the waxing surface treatment and what are its benefits?

Waxing is a surface treatment that applies a lubricating wax coating to the screw surface. This provides enhanced lubrication for smooth installation with reduced driving resistance, particularly beneficial in drywall and gypsum board applications where consistent driving torque is required.

What is the recommended installation depth for this screw?

The screw should be driven to a depth where the countersunk head sits flush with or slightly below the drywall surface without breaking the paper layer. Use torque-controlled drivers or drywall screw setters for consistent depth control.

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.

The step feature provides enhanced seating in countersunk holes. Ensure the countersink angle matches the screw head angle for proper flush mounting.

Use torque-controlled drivers or drywall screw setters to achieve consistent screw depth without breaking the paper surface.

Select the appropriate screw length based on the thickness of drywall layers and framing material. The 80mm length is suitable for multi-layer or thick substrate applications.

Maintain proper screw spacing as specified by building codes and drywall manufacturer recommendations.

The waxing treatment provides lubrication for smooth installation. Handle screws with clean gloves to maintain surface treatment integrity.
