FH4 and FHP Series Self-Clinching Studs are engineered to provide permanent threads in stainless steel sheets that are too hard for standard clinching studs. The core challenge in stainless steel assembly is that the host material is often as hard as, or harder than, the fastener. FH4 (made from 400 series stainless) and FHP (premium hardened alloy) solve this through specialized heat treatment, ensuring they can deform the host metal and lock securely without the stud itself collapsing.

Key Technical Advantages:

• Exceptional Hardness: Capable of being installed into stainless steel sheets with hardness up to 92 HRB (FH4) and even higher with the FHP series.
• Corrosion Resistance: Maintains the integrity of stainless steel assemblies, offering excellent resistance to rust and environmental degradation.
• Flush-Head Design: Ensures the reverse side of the panel remains completely smooth and level after installation, preserving the clean aesthetic of stainless steel.
• High Pull-out & Torque Resistance: Provides a rock-solid attachment that won't loosen even under high vibration or heavy load.
