Screwdriver bit Torx T30 Wera 3867/1 TS SiS stainless steel, 6.3 mm, 1 pc

Wera Torx T30 screwdriver bit model 3867/1 TS SiS is a single 6.3 mm stainless steel bit designed for precise engagement with Torx T30 fasteners. Manufactured by Wera, this bit fits standard 1/4" bit holders and screwdrivers and features a SiS surface treatment that increases wear resistance while preserving accurate tip geometry. The compact, single-piece format makes it convenient to carry as a spare or to install in multi-bit drivers for assembly, maintenance or repair tasks that call for a T30 drive.

Advantages

The SiS surface treatment improves surface hardness and reduces wear, extending service life under repeated use. Made from stainless steel, the bit offers corrosion resistance suitable for varied working environments. The precisely milled Torx geometry ensures secure engagement and reduces the risk of cam‑out, while the 6.3 mm (1/4") shank provides compatibility with widely used bit holders and quick-change adapters.

Suitable for

• Installation and tightening of Torx T30 fasteners in furniture and fixtures
• Mechanical assembly and appliance repair requiring a T30 drive
• Maintenance work on equipment with Torx security or standard fasteners
• Field service and on-site repair where a single reliable replacement bit is needed

Key specifications

• Drive type: Torx T30
• Material: stainless steel
• Surface treatment: SiS (wear-resistant)
• Shank diameter: 6.3 mm (1/4")
• Format: single bit (1 piece)

How to use

Insert the 6.3 mm shank into a compatible 1/4" bit holder, quick-change adapter or screwdriver handle. Align the Torx T30 tip with the screw head and apply steady axial pressure while turning to engage the fastener. For power drivers, use appropriate torque settings to avoid over-tightening; for manual work, ensure firm seating before applying turning force. After use, store the bit in a bit holder or toolbox to protect the SiS surface and tip geometry.

Usage recommendations

Choose the Wera Torx T30 bit when working with Torx T30 screws to ensure a secure fit and to reduce cam‑out. Keep the bit clean and free of debris; replace if the tip shows visible wear or rounding to prevent damage to screw heads. When using in high-torque or impact applications, verify compatibility with your driver and consider using impact-rated bits if required by the task.
