Perfect Stainless Steel Socket Head Cap Screw

SPFS

• Perfect stainless steel has both the equivalence in strength/ toughness to SUS410 and corrosion resistance equivalence of or better than SUS630.
• May be used with any application which necessitates high-strength and high-corrosion resistance.
• Magnetic properties; for applications that utilize magnetic sensors.
• Material/Finish
• YUS-550 (Hardness: 350~450HV)
• Color may vary slightly by production lot.
