## Long description

Dedra SS-M8X40/KL-8.8 is a hex head bolt with an M8 metric thread and a 40 mm shank length, produced to strength class 8.8. It is intended for use in bolted joints where a medium-high tensile strength is required. The bolt features a standard hexagonal head for wrench or socket engagement and is suitable for common mechanical fastening tasks in construction, automotive repair and industrial assembly when paired with appropriate nuts and washers.
Advantages
The hex head design allows reliable torque application with spanners or sockets for secure clamping. Strength class 8.8 provides a defined combination of tensile strength and yield, offering higher load capacity than lower-grade fasteners while remaining compatible with typical steel components. The M8 × 40 size is a commonly available dimension that simplifies sourcing of matching nuts and washers and integrates well into threaded assemblies and machine parts.
Suitable for
Mechanical assembly of machines and equipment
Structural connections in light to medium construction
Automotive repairs and component fastening
Maintenance and replacement of threaded fasteners
Key specifications
Thread size: M8 (metric)
Length: 40 mm (shank length)
Head type: hexagonal head for wrench or socket
Strength class: 8.8 (medium-high tensile strength)
Intended use: general-purpose steel bolted joints with matching nuts and washers
How to use
Select a compatible nut and washer sized for M8 thread and ensure mating threads are clean and undamaged. Insert the bolt through aligned holes of the components to be joined, place the washer and engage the nut. Tighten using an appropriate spanner or socket to the torque recommended for 8.8 grade M8 fasteners for the specific application and material. Inspect the joint after tightening for proper clamp and re-torque as required by maintenance schedules or application standards.
Usage recommendations
For structural or safety-critical connections, follow relevant engineering guidelines for torque values, preloading and thread engagement. Use corrosion-resistant coatings or suitable materials if exposed to moisture or corrosive environments, and replace bolts showing signs of wear, corrosion or thread damage.
