Key Features
-
Flush-Fit Head Design: The flat, countersunk head sits level with or below the surface, providing a smooth, unobtrusive finish suitable for tight or moving assemblies.
-
Standard Coarse Thread: The 0.7mm pitch ensures strong thread engagement while simplifying installation and minimizing vibration-related loosening.
-
Precision Torque Control: The internal hex socket allows secure torque application and reduces tool slippage, even in confined or recessed spaces.
-
Durable and Corrosion-Resistant: Available in stainless steel or protective coatings such as zinc or black oxide for enhanced longevity in harsh or outdoor conditions.
-
Compact Strength and Aesthetic Appeal: Engineered for applications that demand both mechanical reliability and a clean, low-profile finish.
Typical Applications
The M4-0.7 Flat Head Socket Cap Screw is ideal for:
-
Precision machinery and equipment with flush or aesthetic surfaces
-
Electronics and enclosures where compact fasteners are essential
-
Automotive, motorsport, and powersports components requiring low-profile hardware
-
Robotics, automation, and aerospace systems with space or clearance constraints
-
Bicycles, instruments, and mechanical assemblies
-
Custom builds, prototypes, and fabrication projects where both performance and appearance matter
