Wood screw Koelner/Rawlplug TS-3516 3.5x16 mm countersunk head TX drive

Koelner/Rawlplug TS-3516 wood screw, size 3.5x16 mm, features a countersunk (conical) head and a TX (Torx) drive designed for secure fastening in solid wood and wood-based materials. The screw’s geometry and thread profile provide reliable clamping force while the countersunk head allows a flush finish with the material surface, making it suitable for visible assemblies where a neat appearance is required.

Advantages

The countersunk head ensures the screw sits flush in the workpiece, reducing the need for additional finishing. The TX drive improves torque transfer and reduces cam-out compared with slotted or Phillips drives, enabling faster and more controlled installation with compatible Torx bits. The 3.5 mm diameter and 16 mm length balance penetration and holding power for typical furniture and carpentry joints.

• Столярные работы и внутренние деревянные конструкции
• Панели и деревянные плиты (ДСП, МДФ) при условии предварительного сверления по необходимости
• Ремонт и мелкие монтажные работы по дереву

Key specifications

• Diameter: 3.5 mm
• Length: 16 mm
• Head type: countersunk (conical)
• Drive type: TX (Torx)
• Intended material: wood and wood-based materials
• Finish: suitable for flush mounting

How to use

Pre-select a Torx bit that matches the screw’s TX drive size and use a hand screwdriver or powered driver set to an appropriate torque. For dense hardwoods or when splitting is a risk, drill a pilot hole slightly smaller than the screw core diameter. Position the screw so the head seats evenly and drive until the countersunk head is flush with the surface. Avoid excessive torque to prevent stripping the drive or over‑sinking the head.

Usage recommendations

Use compatible Torx bits and adjust driver torque according to material density. For exterior or moisture-prone applications, select screws with appropriate corrosion-resistant coatings; for indoor furniture and cabinetry the standard finish is usually sufficient. When working with thin panels, consider using shorter screws or additional backing to prevent breakthrough.
