Hex Head Bolt No name SS-M8X50/KL-8.8, M8 x 50 mm, strength class 8.8, steel

Hex head bolt No name SS-M8X50/KL-8.8 is a steel fastener with a metric M8 thread and a 50 mm shank length. Produced to strength class 8.8, this bolt delivers medium-high tensile strength suitable for mechanical assemblies and structural connections. The hex head design allows for secure torque application with standard wrenches or sockets, providing dependable threaded engagement in machinery, construction joints, and repair tasks.

Advantages

The bolt's strength class 8.8 offers a balance between strength and machinability for general industrial use. Steel construction provides good shear and tensile resistance under typical working loads. The hex head format ensures easy installation and removal with commonly available tools, enabling consistent clamping force. Manufactured to metric dimensions, the fastener integrates with standard M8 nuts and threaded holes, simplifying replacement and compatibility in mixed-component assemblies.

Suitable for

• Mechanical assemblies in machinery and equipment
• Structural and metal frame connections
• Repair and maintenance tasks requiring medium-high strength fasteners
• Joining components where a hex head drive is preferred

Key specifications

• Thread: metric M8
• Length: 50 mm (shank length)
• Material: steel
• Strength class: 8.8 (medium-high tensile strength)
• Head type: hex head for wrench or socket drive

How to use

Select a matching M8 nut or tapped hole and position the bolt through the components to be joined. Use an appropriate wrench or socket sized for the hex head to tighten the bolt, applying torque according to the requirements of the assembly and strength class 8.8. For joints requiring precise clamping force, use a calibrated torque wrench and follow manufacturer or engineering specifications. When reusing bolts, inspect for thread damage, corrosion, or elongation and replace if any defects are found.

Usage recommendations

For optimal performance, pair the bolt with compatible grade nuts and washers rated for medium-high strength. Apply thread lubricant or anti-seize where specified to achieve consistent torque readings and to reduce galling during installation. Avoid exceeding recommended torque values to prevent overstressing the fastener.
