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.
Hexagon Flange Nut
Hex Flange Nuts: Overview
Material:
- Common materials: Carbon steel (Grade 8.8/10.9), stainless steel (304/316), alloy steel (heat-treated), or brass.
- Surface treatments: Zinc plating, hot-dip galvanizing, Dacromet coating, or passivation (stainless steel) for corrosion and wear resistance.
Manufacturing Process:
- Cold Heading: Forms the hexagonal base and flange from metal wire.
- Thread Rolling: Precision internal threading (metric/SAE) using dies.
- Flange Forming: The integrated flange is forged or stamped around the nut base.
- Heat Treatment: Applied to carbon/alloy steel to enhance hardness and tensile strength.
- Surface Finishing: Electroplating or coating for corrosion protection.
Key Production Considerations:
- Flange flatness: Ensures even load distribution and prevents tilting during tightening.
- Thread concentricity: Aligns perfectly with the bolt axis to avoid cross-threading.
- Material hardness: Balances ductility and strength (e.g., Grade 10.9 for high-stress use).
- Coating uniformity: Prevents buildup on threads or flange edges.
Applications:
- Automotive: Engine mounts, exhaust systems, and chassis assemblies.
- Machinery: Secures rotating parts, motors, and conveyor systems under vibration.
- Structural: Joins steel beams, frameworks, and seismic bracing.
- Electronics: Fastens enclosures, panels, and heat sinks with vibration resistance.
- HVAC: Ducting and equipment requiring anti-loosening properties.
Installation:
- Tool selection: Use a wrench or socket matching the hex size (e.g., 17mm, ¾”).
- Alignment: Hand-tighten the nut onto the bolt to ensure proper thread engagement.
- Torque application: Tighten to manufacturer-specified torque using a calibrated wrench.
- Flange contact: Ensure the flange sits flush against the mating surface for optimal load distribution.
- Inspection: Check for even flange compression and no thread damage post-installation.
Note:
- Vibration resistance: The flange acts as a built-in washer, reducing loosening in dynamic environments.
- Material pairing: Match nut and bolt grades (e.g., Grade 10.9 nut with Grade 10.9 bolt).
- Reuse limits: Avoid reusing nuts with deformed flanges or stripped threads.
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.
A: Yes,we are very glad to offer you samples.
However the express courier cost from our company to your required address will be upon your account.
Usually we use DHL, UPS, FEDEX or EMS as the courier.
It will take 3-7 days to arrive many Europe countries and North America.
Which express courier we will use, it’s up to your convenient or the express charge.
