Hex Head Bolt Niczuk M10x25mm, 6-point, Metric M10 x 25

Hex Head Bolt Niczuk M10x25mm, 6-point, Metric M10 x 25 is a standard metric fastener with an M10 thread diameter and a 25 mm shank length. The bolt features a six-point (hex) head designed for use with standard wrenches and sockets. It is intended for general assembly and fastening tasks in metal and wooden structures, machinery mounting, and construction where a reliable M10 x 25 metric bolt is required.

Advantages

The six-point hex head provides good torque transfer and secure engagement with tools, reducing the likelihood of rounding under normal tightening. Metric M10 threading offers compatibility with common nuts and tapped holes in metric systems. The 25 mm length suits medium-thickness assemblies, giving sufficient thread engagement while keeping protrusion minimal. Manufactured to standard dimensions, the bolt simplifies selection for repairs and new builds where M10 hardware is specified.

Suitable for

• Fastening metal frames, brackets, and profiles
• Joining wooden assemblies with corresponding nuts or threaded inserts
• Mounting machinery components and fixtures
• General construction and maintenance tasks using metric fasteners

Key specifications

• Thread diameter: M10 (metric)
• Shank length: 25 mm
• Head style: 6-point hex (hexagonal)
• Drive method: wrench or socket
• Application: general-purpose fastening for metal and wood

How to use

Select a matching M10 nut or a tapped M10 hole and align components to be fastened. Insert the bolt through aligned holes and engage the nut by hand to avoid cross-threading. Use an appropriate sized wrench or socket to tighten the hex head to the required torque, observing any torque specifications for the materials and joint design. For improved joint security, consider using a washer and a locking method such as a lock washer or thread-locking compound where vibration or loosening is a concern.

Usage recommendations

Verify material compatibility and required torque values before installation. Use appropriate personal protective equipment when working with tools. For critical or load-bearing applications, confirm bolt grade and tensile strength are suitable; if unspecified, consult technical documentation or choose fasteners with certified mechanical properties.
