Hex Head Bolt Niczuk M12 x 100 mm, 6-sided, DIN-style fastener

Hex head bolt Niczuk M12 x 100 mm is a general-purpose metric fastener with a six-sided head designed for mechanical assemblies, construction connections and repair tasks. The bolt provides a standard M12 threaded shaft at 100 mm length and is intended for use with compatible nuts and washers. It is compatible with common metric hand and power tools for installation and removal.

Advantages

This Niczuk hex head bolt offers a standardized thread profile and nominal dimensions that simplify interchangeability with other M12 hardware. The six-sided head allows secure torque application with wrenches and sockets, helping to achieve reliable clamping force. Its simple, proven design makes it suitable for routine maintenance and structural connections where a metric M12 × 100 fastener is specified.

Suitable for

• Mechanical assemblies and machinery fastening
• Construction and structural connections
• Repair and maintenance of equipment and vehicles
• Joining metal parts with corresponding nuts and washers

Key specifications

• Thread size: M12 (metric)
• Length: 100 mm (threaded shaft length as specified)
• Head style: 6-sided (hex) head for wrench or socket drive
• Application: general-purpose fastening for metal and structural joints
• Compatibility: designed for use with standard M12 nuts and washers and metric tools

How to use

Select a matching M12 nut and appropriate washer for the load and material. Insert the bolt through aligned parts, place the washer and thread the nut by hand to engage threads. Use a correctly sized wrench or socket to tighten to the required torque per application or material specifications. For removal, loosen with the same metric tool and back the nut off before extracting the bolt. Ensure threads are clean and undamaged before installation to maintain proper clamping and to avoid cross-threading.

Usage recommendations

Use corrosion-resistant washers or coated fasteners in outdoor or corrosive environments. Follow torque specifications for the connected materials and, where applicable, apply thread locker or locking washers for vibration-prone assemblies.
