304 stainless steel flange nut

The fastening and opening of bolts and nuts adopts non-standard design, and the matching
non-standard tools are used to solve the opening and fastening problems. In general, other
wrenches cannot be inserted. In the appearance design of nuts and bolts, non-standard slotting,
opening or pentagonal, heptagonal, nine-corner or custom-made corresponding groove tools
have played a very good anti-theft effect

عملية الرأس على البارد هي واحدة من العمليات الجديدة للتشغيل الآلي بالضغط ذات القطع الأقل أو بدون قطع
المعدن. وهي طريقة معالجة تستخدم التشوه البلاستيكي للمعدن تحت تأثير
قوى خارجية، وبمساعدة القوالب، تقوم بإعادة توزيع ونقل حجم المعدن لتشكيل
الأجزاء أو الفراغات المطلوبة. عملية الخراطة على البارد هي الأكثر ملاءمة لإنتاج الأجزاء القياسية
أدوات التثبيت مثل البراغي والبراغي والصواميل والمسامير والمسامير والدبابيس وغيرها

304 Stainless Steel Flange صامولة – Complete Overview

1. Definition & Purpose

A 304 stainless steel flange nut is a hex nut with an integrated circular flange that acts as a built-in washer. It is made from Type 304 (A2) austenitic stainless steel, offering excellent corrosion resistance, durability, and moderate strength.

إن “304” designation refers to its material composition (18% chromium, 8% nickel), while “flange” indicates its wide, load-distributing base.

2. Material Properties

• Corrosion Resistance:

  • Resists rust, oxidation, and mild chemicals.

  • Suitable for food processing, marine, and outdoor applications (but not constant saltwater exposure—316/A4 is better).

• Non-Magnetic (Mostly):

  • Generally non-magnetic but may become slightly magnetic after cold forming.

5. Standards & Compliance

• ISO 3506 (Stainless steel fastener mechanical properties).

• DIN 6923 (Metric serrated flange nuts).

• ASME B18.2.2 (Imperial flange nuts).

• FDA Compliance (For food-grade applications).

8. Limitations

• Not for Extreme Chloride Exposure (e.g., seawater immersion—choose 316/A4 instead).

• Lower Strength than high-grade alloy steel nuts.

• Higher Cost than zinc-plated or carbon steel nuts.

Conclusion

إن 304 stainless steel flange nut is a versatile, corrosion-resistant fastener ideal for moderate-strength applications where rust prevention and vibration resistance are key. It is widely used in automotive, construction, food processing, and plumbing.

For harsher environments (e.g., seawater, acids), consider 316/A4 stainless steel flange nuts.
