Product Introduction

The Semi Countersunk Hexalobular Six-Bevel Rib Chipboard Screw Double Type 17 Torx is a specialized fastener designed for chipboard, particle board, and engineered wood applications requiring a low-profile finish with enhanced drive engagement and superior holding power. The semi countersunk head provides a slightly raised profile that offers a clean appearance while providing adequate bearing surface for chipboard assemblies. The hexalobular six-bevel rib drive enables positive torque transmission with reduced cam-out risk during installation, providing reliable engagement with standard hexalobular Torx tools. The Type 17 thread features a specialized buttress profile that reduces driving torque while maintaining pull-out resistance in chipboard substrates. The double thread design provides faster installation with improved holding power and reduced driving torque. Manufactured from SUS304 stainless steel with brightening surface treatment, this screw provides general corrosion resistance with an aesthetic bright finish. The 5.0-3.0 thread specification with 60mm length offers extended engagement for chipboard and engineered wood assemblies requiring additional depth.

Common Questions and Solutions

What is the semi countersunk head design?

The semi countersunk head provides a slightly raised profile compared to fully countersunk heads. This design offers a clean appearance while providing adequate bearing surface for secure clamping in chipboard and engineered wood applications.

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

The Type 17 thread features a specialized buttress profile that reduces driving torque while maintaining pull-out resistance. The double thread provides faster installation with improved holding power and reduced driving torque for efficient chipboard fastening.

What is the recommended hexalobular driver size for this screw?

Select a hexalobular (Torx) driver that matches the six-bevel rib head size specified for the 5.0-3.0 thread. Using the correct driver size prevents driver slippage and ensures optimal torque transfer. Refer to the product specification for the exact size.

What is the recommended pilot hole size for chipboard screws?

Pilot hole size varies based on screw diameter and chipboard density. Refer to the technical datasheet for recommended pilot hole diameters to ensure proper thread engagement and prevent material splitting.

What is the brightening surface treatment?

Brightening is a surface treatment process that enhances the natural finish of the stainless steel material. It provides a bright, aesthetic appearance while improving surface smoothness and corrosion resistance through removal of surface contaminants and oxidation.

What is the recommended installation torque for this screw?

Installation torque varies based on chipboard density and application. The double Type 17 thread is designed for efficient driving. Use torque-controlled drivers to prevent over-tightening. Consult the technical datasheet for recommended torque values.

Installation Considerations

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

The semi countersunk head provides a clean appearance with adequate bearing surface. The double Type 17 thread is designed for efficient driving in chipboard.

Drill pilot holes to the recommended diameter for the 5.0-3.0 thread size and chipboard density to prevent splitting and ensure proper thread engagement.

Use torque-controlled drivers to prevent over-tightening. The head should seat properly without damaging the chipboard surface.

Select the appropriate screw length based on material thickness. The 60mm length is suitable for thick chipboard assemblies and engineered wood products.

The brightening treatment provides aesthetic and corrosion protection. Handle screws with clean gloves to maintain surface appearance and prevent contamination.
