## Long description

Hexagon head bolt DELTA-OPTI M8x20 8.8 is a metric fastener designed for mechanical and construction applications. Featuring an M8 thread and a 20 mm shank length, this bolt conforms to strength class 8.8 and is intended for use with compatible nuts and washers. It provides secure clamping for steel assemblies, machinery components and structural joints where medium-high tensile strength and reliable clamping are required.
Advantages
The 8.8 strength class combines good tensile strength and hardness for repeated use in mechanical assemblies. The hexagon head allows for straightforward installation with standard spanners or sockets, enabling consistent torque application. Its standardized M8 thread and 20 mm length make it compatible with common nuts and washers, simplifying inventory and replacement. The bolt is suitable for situations where robust steel-to-steel connections are needed without resorting to higher-grade fasteners.
Suitable for
Assembly of steel frames and structural elements
Mounting machinery parts and equipment
Joining metal panels and brackets
Repair and maintenance of vehicles and agricultural machinery where medium-high strength is sufficient
Key specifications
Thread size: M8
Length: 20 mm (shank)
Head type: hexagon (hex head)
Strength class: 8.8
Material: steel
Drive method: wrench/socket
How to use
Select a compatible nut and, if required, a washer suitable for the application and material pairing. Insert the bolt through the aligned holes of the parts to be joined, place the washer and thread on the nut, then tighten using an appropriate spanner or socket. Apply torque according to the joint design and material specifications to achieve the required clamping force without exceeding the bolt's allowable torque. For assemblies subject to vibration, use a locking washer or a locking nut where necessary.
Usage recommendations
Store bolts in a dry environment to avoid corrosion. For critical or safety-related assemblies, verify torque values and periodic inspection intervals. When joining dissimilar metals, consider appropriate washers or coatings to prevent galvanic corrosion.
