Description
The M12-1.75 Flat Head Socket Cap Screw is a high-strength precision fastener engineered for demanding applications that require a flush, countersunk finish combined with maximum structural integrity. Its flat head profile and internal hex drive enable accurate torque application, a secure fit, and a clean, recessed surface, making it ideal for heavy-duty assemblies where aesthetics and strength must coexist.

Key Features
Flush-Fit Head Design:
The flat, countersunk head sits flush with or below the surface, ensuring a smooth, unobtrusive finish ideal for assemblies requiring low-profile or aerodynamic surfaces.
Standard Coarse Thread:
The 1.75 mm pitch provides robust thread engagement, reducing the risk of loosening under high vibration or dynamic loads.
Precision Torque Control:
The internal hex drive offers reliable torque transmission, allowing secure tightening even in recessed or restricted spaces.
Exceptional Strength and Corrosion Resistance:
Available in alloy steel for high tensile strength or stainless steel for maximum corrosion protection in outdoor or industrial environments.
Professional and Durable Finish:
Designed to combine mechanical performance with a refined appearance for visible or precision-engineered assemblies.
