Description
The M24-3.0 Flat Head Socket Cap Screw is a heavy-duty precision fastener engineered for the most demanding structural, industrial, and mechanical applications. Designed for exceptional load-bearing performance with a flush, countersunk finish, it combines the strength of a large-diameter fastener with the refined precision of an internal hex drive. This makes it ideal for large assemblies where strength, safety, and surface finish are all critical considerations.
Specifications

Key Features
Flush-Fit Head Design:
The flat, countersunk head sits even with or below the surface, offering a smooth and unobtrusive finish that’s essential in applications where clearance, aerodynamics, or visual appeal matter.
Standard Coarse Thread:
The 3.0 mm pitch provides maximum thread engagement and strong load distribution, ensuring secure fastening even under high dynamic or vibrational stress.
High Torque Transmission:
The internal hex drive enables consistent and controlled torque application, ensuring reliable tightening and minimizing the risk of rounding or slippage during installation.
Engineered for Strength and Endurance:
Manufactured from high-grade alloy steel for superior tensile performance, with stainless steel options for corrosion resistance in marine, outdoor, or chemical environments.
Industrial Finish Options:
Available in a variety of finishes including black oxide for reduced glare, zinc plating for corrosion resistance, or full stainless for maximum longevity and professional presentation.
