Screwdriver bit holder Topex 1/4" 210 mm model 39D860

Topex screwdriver bit holder 1/4" 210 mm model 39D860 is an extended bit holder designed to accept standard 1/4" hex bits and provide additional reach for fastening and loosening screws in narrow, recessed, or deep-access locations. The 210 mm length increases accessibility while maintaining a secure connection between the driver and interchangeable bits for assembly, repair, and maintenance tasks.

Advantages

The bit holder offers extended reach without significant loss of control thanks to its straight 210 mm shaft and universal 1/4" hex receptacle. Its construction ensures stable bit retention during torque application and reduces the need to disassemble surrounding elements to reach fasteners. The design supports rapid bit changes and compatibility with a wide range of screwdriver bits and power or manual drivers that accept 1/4" hex holders.

Suitable for

• Reaching screws in deep or recessed mounting points
• Assembly and mechanical maintenance in confined spaces
• Automotive and electrical repair where extra length is required
• Use with manual drivers or power screwdrivers that accept 1/4" bits

Key specifications

• Bit shank size: 1/4" hex
• Overall length: 210 mm
• Function: bit holding and extension for fastening tasks
• Compatibility: standard 1/4" hex screwdriver bits and compatible drivers

How to use

Insert a compatible 1/4" hex screwdriver bit into the holder's receptacle until it seats securely. Attach the bit holder to a manual driver or power driver with a matching 1/4" hex socket or chuck. Position the extended shaft so the bit reaches the fastener, apply steady axial pressure, and turn the driver at appropriate speed and torque for the fastener and material. When finished, withdraw the holder and remove the bit by pulling it from the receptacle or using the release mechanism if present.

Usage recommendations

Use the Topex 1/4" 210 mm bit holder with appropriately sized bits and correct torque settings to avoid bit slipping or fastener damage. For power drivers, select moderate speed and controlled torque when accessing screws in tight or delicate assemblies. Inspect the holder and bits for wear before use and replace any worn bits to maintain a secure fit and safe operation.
