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.
Eye Bolt
Eye Bolts: Overview
Material:
- Common materials: Stainless steel (Grade 304/316 for corrosion resistance), carbon steel (Grade 4.8/8.8 for general use), alloy steel (heat-treated for high strength), or hot-dip galvanized steel.
- Surface treatments: Zinc plating, Dacromet coating, or passivation (for stainless steel) to enhance durability and corrosion resistance.
Manufacturing Process:
- Forging: Hot or cold forging to shape the eye (loop) and shank, ensuring structural integrity and load-bearing capacity.
- Machining: Precision drilling of the eye and threading of the shank (metric or unified threads).
- Heat Treatment: Quenching and tempering (for carbon/alloy steel) to achieve desired tensile strength and hardness.
- Surface Finishing: Coating application via electroplating, hot-dip galvanizing, or mechanical polishing.
Key Production Considerations:
- Eye geometry: Smooth, radiused edges to prevent cable/rope abrasion.
- Thread accuracy: Ensures compatibility with nuts and load distribution.
- Load rating compliance: Strict adherence to SWL (Safe Working Load) standards (e.g., DIN 580, ASME B18.15).
Applications:
- Lifting/rigging: Overhead cranes, stage rigging, cargo securing, and marine equipment.
- Anchoring: HVAC systems, machinery tie-downs, and structural supports.
- Industrial: Temporary lifting points in construction, transportation, and energy sectors.
Installation:
- Alignment: Ensure the shank is fully threaded into the mounting surface (avoid side-loading).
- Load direction: Use shoulder-type eye bolts for angular loads; non-shouldered versions only for vertical loads.
- Torque: Tighten nuts to specified torque values to prevent thread stripping.
- Safety check: Verify SWL markings and avoid exceeding angular load limits (typically ≤45° for shouldered bolts).
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.
