Square lock 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

Square lock nuts are a type of locking nut designed to resist loosening under vibration and torque. They are commonly used in industrial and mechanical applications where secure fastening is critical. Here’s a detailed description:

Features of Square Lock Nuts:

1. Shape – As the name suggests, these nuts have a square profile instead of the typical hexagonal shape, providing a larger surface area for gripping with wrenches or other tools.

2. آلية القفل – They often incorporate a locking feature such as:

   • Nylon Insert (PAL Nut) – A nylon ring inside the nut creates friction against the bolt threads to prevent loosening.

3. المواد – Typically made from steel (plain, zinc-plated, or stainless steel), brass, or nylon for corrosion resistance and durability.

المزايا:

• مقاومة عالية لعزم الدوران – The square shape allows for better grip and higher torque application.

• مقاومة الاهتزازات – The locking mechanism prevents loosening in high-vibration environments (e.g., machinery, automotive, and aerospace applications).

• No Need for Additional Lock Washers – The built-in locking feature eliminates the need for separate lock washers in many cases.

Installation Notes:

• Should be tightened to the recommended torque specifications.

• Nylon-insert types may lose effectiveness after repeated use due to wear.

• Serrated base types require a clean, flat surface for optimal grip.
