What Buyers Should Know Before Sourcing Stainless Steel Carriage Bolts
تأكيد أبعاد الرأس والرقبة
Carriage bolts use a round or mushroom head with a square neck under the head to help prevent rotation during tightening. Buyers should confirm head diameter, head height, square neck size, neck height, thread length, total length and thread pitch before production. XZ Fastener’s stainless steel carriage bolts product reference can help when preparing a size list or drawing-based inquiry.
Select stainless grade by environment
304 stainless steel is widely used for general outdoor assemblies, equipment frames and furniture hardware. 316 or A4 stainless steel is preferred when the bolts will face coastal air, chlorides, marine exposure or stronger corrosion risk.

شرح المواد والصف
Stainless steel carriage bolts are selected when buyers need anti-rotation fastening with better corrosion resistance than carbon steel. 304 stainless steel is commonly used for general outdoor equipment, furniture, timber structures and light industrial assemblies. 316 stainless steel contains molybdenum and is often preferred for coastal, marine, chemical and chloride-exposed environments.
A2 and A4 are common stainless grade families in metric fastener purchasing. A2-70 and A4-70 are frequently requested for stainless bolts where mechanical performance and corrosion resistance must be balanced. For more detail, XZ Fastener provides a guide to درجات A2-70 وA4-70 وA4-80 فولاذ مقاوم للصدأ.

التصنيع ومراقبة الجودة
Stainless steel carriage bolts are typically produced through wire preparation, heading, square neck forming, threading, surface treatment, inspection and packing. Depending on size, grade and drawing requirement, production may involve cold heading, machining or a combined process. The square neck must be formed consistently so the bolt resists rotation during tightening.
Quality control may include diameter checking, length tolerance, head diameter, head height, square neck dimensions, thread gauge inspection, surface appearance, material verification, hardness or tensile checks when required, and packing inspection. Buyers comparing carriage, flange, hex and other bolt styles can review XZ Fastener’s bolt types explained دليل.
