A: It depends.If we have bulk goods in stock, we can ship goods within 3 days after the QC process. If we don’t have stock, normally it takes 7-15 days for OEM samples and 20-30 days for bulk goods. If it refers to opening the new mold, it takes an extra 7-15 days to make the mold.
Hex Nuts
Hex Nuts: Overview
Material:
- Common materials: Carbon steel (Grade 4/8/10), stainless steel (304/316), alloy steel (heat-treated for high strength), brass, or nylon.
- Surface treatments: Zinc plating, hot-dip galvanizing, Dacromet coating, or passivation (stainless steel) for corrosion resistance.
Manufacturing Process:
- Cold Forging: Shapes the hexagonal blank from steel wire, ensuring dimensional consistency.
- Threading: Internal threads are cut via tapping or formed by thread rolling for precision.
- Heat Treatment: Quenching and tempering (for high-grade steel nuts) to enhance hardness and tensile strength.
- Surface Finishing: Electroplating, galvanizing, or coating to improve durability and corrosion resistance.
Key Production Considerations:
- Thread accuracy: Must comply with ISO/DIN standards to ensure compatibility with bolts.
- Hexagon symmetry: Uniform flat-to-flat dimensions for proper wrench engagement.
- Coating uniformity: Prevents thread clogging and ensures smooth installation.
- Deburring: Eliminates sharp edges to avoid thread damage during assembly.
Applications:
- Industrial machinery: Secures bolts in engines, conveyors, and presses.
- Construction: Used in steel frameworks, bridges, and scaffolding.
- Automotive: Fastens chassis, suspension, and engine components.
- HVAC/piping: Joins flanges and pipe fittings with lock nuts (e.g., nylon insert) for vibration resistance.
- Consumer goods: Assembly of furniture, bicycles, and electronics.
Installation:
- Tool selection: Use a wrench or socket matching the nut’s hex size (e.g., 10mm, ½”).
- Alignment: Ensure threads are clean and undamaged; hand-tighten before applying torque.
- Torque control: Follow manufacturer specifications to avoid under/over-tightening (use a torque wrench for critical joints).
- Locking mechanisms: Pair with lock washers, thread-locking adhesives, or nylon-insert nuts in high-vibration environments.
- Inspection: Check for proper seating and thread engagement post-installation.

Frequently Asked Questions
A: Normally, we make a 30% deposit after Pl confirmation and a 70% balance before shipment. lf order amountis too small, we can also change to 100% deposit in order to save bank handling charge.
A: A pre-bulk sample check can solve this problem to the largest extent. We will arrange production according to the pre-bulk sample quality standard after your confirmation of the samples.
A: We are not only a trading company but also a manufacturer. Our factory mainly focuses on mold design and quality inspection. Our bulk production may come from the factories we have worked with for a long time, and they are all ISO9001 certified. Through this cooperation model, we can not only ensure product quality and service, but also satisfy the diversified product needs of customers, and the price is more advantageous.
