Self-drilling screw Dedra M6 L14 stainless steel with groove

Self-drilling screw Dedra M6 L14 stainless steel with groove is a stainless steel fastener combining an integrated drill tip and a longitudinal groove to assist chip evacuation and reduce driving torque. The M6 thread and 14 mm overall length make this screw suitable for joining thin metal sheets or attaching metal to wood without prior pilot holes, while the corrosion-resistant stainless construction enables use in both interior and exterior environments.

Advantages

The integrated drill tip eliminates the need for separate drilling, saving time on installation and ensuring consistent hole sizes. The groove improves material penetration and helps remove swarf during driving, reducing the risk of jamming and improving seating accuracy. Stainless steel construction provides corrosion resistance, extending service life in humid or outdoor conditions and minimizing maintenance. Standard M6 thread form delivers reliable clamping force in common metal and wood applications.

Suitable for

• Fastening thin metal sheets to metal substructures
• Attaching metal components to wood or composite substrates
• Light structural connections in exterior and interior assemblies
• Applications where pre-drilling is impractical or time-consuming

Key specifications

• Material: stainless steel for corrosion resistance
• Thread size: M6
• Length: 14 mm overall
• Integrated drill point for self-drilling installation
• Longitudinal groove for improved chip evacuation and reduced torque

How to use

Select an appropriate driver or bit that matches the screw head drive type and secure the screw in the driver. Position the integrated drill tip at the intended fastening point and apply steady rotational speed with moderate axial pressure. Allow the self-drilling action to create the hole and then continue driving until the screw head seats flush or to the required torque. For best results, use controlled speed and avoid excessive overtightening to prevent material deformation.

Usage recommendations

Use protective eyewear when installing self-drilling screws to guard against flying chips. For thicker materials, consider confirming required penetration depth and, if necessary, pre-drill or select a longer fastener. When fastening dissimilar metals, use appropriate separation or coatings to reduce risk of galvanic corrosion despite the stainless construction.
