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
Pan Head Chicago Screws (also known as sex bolts, binding posts, or barrel nuts) are a type of two-part fastener consisting of a male screw (threaded bolt) and a female barrel nut (threaded sleeve). They are designed to securely join materials together without the need for a traditional nut on the backside.
الميزات الرئيسية:
-
Pan Head Design – The screw has a slightly rounded, low-profile head with a flat bearing surface, providing a smooth finish while distributing pressure evenly.
-
Internal Threading – The barrel nut (female component) has internal threads that accept the male screw, creating a flush or semi-flush fastening.
-
Secure Fastening – Unlike standard screws and nuts, Chicago screws remain tightly fastened, reducing loosening from vibration or movement.
-
Non-Protruding Back – The barrel nut sits inside a pre-drilled hole, leaving a clean finish on both sides of the assembly.
Common Materials:
-
Stainless Steel (rust-resistant, durable)
-
Brass (corrosion-resistant, decorative)
-
Aluminum (lightweight, non-magnetic)
-
Nylon/Plastic (non-conductive, lightweight)
التطبيقات:
-
Leathercraft (belts, holsters, bags, saddles)
-
Furniture & Cabinetry (chairs, panels, modular systems)
-
Bookbinding & Albums (swatch books, sample binders)
-
Industrial & Machinery (panels, covers, fixtures)
-
Signage & Displays (secure yet removable fastening)
Pan Head Chicago Screws are ideal for applications requiring a strong, flush-mount fastener with a professional appearance. They are widely used in industries where traditional nuts and bolts are impractical.
