What are the specifications of the M24-3 x 60mm socket cap screw?
Thread size and length
The screw has a thread size of M24-3 and a length of 60mm. It is fully threaded, meaning threads run the entire length of the shank.
Material and finish
Made from Class 8.8 alloy steel with a thermal black oxide finish. This finish provides moderate corrosion resistance and a non-reflective surface.
Drive type
Features a hex socket drive, requiring a hex key (Allen wrench) for installation and removal.
Pack quantity
Sold in packages of 10 pieces.
What are the recommended applications for these screws?
Suitable uses
These socket cap screws are well suited to machinery, tooling, jigs, and precision assemblies where high strength and a flush profile are needed.
Not recommended for
The thermal black oxide finish does not provide the corrosion resistance of stainless steel or zinc plating. Avoid outdoor or wet environments unless additional protection is applied.
How should torque be applied to M24-3 x 60mm socket cap screws?
General torque guidelines
The catalog does not specify exact torque values. For Class 8.8 alloy steel fasteners, torque should be based on thread size and material condition. Always consult the manufacturer's specifications for the specific assembly.
Importance of proper torque
Incorrect torque can lead to fastener failure or damage to the assembly. Use a calibrated torque wrench and follow the equipment manufacturer's instructions.

What are the limitations of the thermal black oxide finish?
Corrosion resistance
Thermal black oxide offers mild corrosion protection. It is not suitable for highly corrosive or marine environments. For such applications, consider stainless steel or coated fasteners.
Aesthetic considerations
The finish provides a matte black appearance, which can be desirable for visual consistency in assemblies.
What is the grade of these socket cap screws?
Class 8.8 alloy steel
Class 8.8 is a medium-strength grade commonly used in general engineering. It offers a good balance of strength and ductility for many applications.
Strength considerations
While Class 8.8 is strong, higher grades (e.g., 10.9 or 12.9) are available for extreme loads. The catalog does not list load capacities, so verify with the manufacturer for critical applications.
