Features a cylindrical head with internal hex drive for secure torque application and compact installation in confined spaces.

## Long description

Hex Socket Head Cap Screw Dedra SI‑M8X25/KL‑8.8 is a metric fastener with M8 diameter and 25 mm length, manufactured to strength class 8.8. It features a cylindrical head with an internal hex drive (Allen) that allows secure torque transfer and compact installation in confined assemblies. The screw is intended for bolted joints requiring elevated tensile strength and reliable clamping in machinery, metalworking and general assembly applications.
Advantages
This hex socket head cap screw provides a high strength-to-size ratio due to its 8.8 grade, offering improved tensile and yield properties compared with lower-strength fasteners. The internal hex drive reduces the risk of cam-out and permits installation where external wrench clearance is limited. Its cylindrical head design gives a neat, low-profile finish and allows for countersunk or recessed mounting in housings and machine frames.
Suitable for
Fixing components in industrial machinery and equipment
Metal fabrication and structural connections
Assembly of cabinets, housings and enclosures with limited external access
Maintenance and repair tasks requiring reliable threaded joints
Key specifications
Thread size: M8
Length: 25 mm (threaded portion overall length)
Strength class: 8.8 (medium-high tensile strength)
Head type: cylindrical socket head (internal hex drive)
Drive: hex (Allen) for torque-controlled tightening
How to use
Select a matching M8 threaded hole or nut and ensure mating threads are clean and undamaged. Use an appropriately sized Allen key or hex bit to engage the internal drive fully and apply torque according to the material and joint design; refer to relevant torque specifications for strength class 8.8 fasteners. Do not exceed recommended torque to avoid overstressing the screw. For repeated assemblies, inspect threads for wear and replace damaged fasteners to maintain joint integrity.
Usage recommendations
For optimal performance, pair the screw with compatible M8 nuts or tapped threads and, where vibration is present, consider using a locking method (locking washer, threadlocker or prevailing torque nut). When assembling into thin or soft materials, use a backing plate or distributed clamp to prevent pull-through and ensure even load distribution across the joint.
