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.
Square Taper Washer
Square Beveled Washers: Overview
Materials:
- Carbon steel (common for high-strength applications, often galvanized or zinc-plated), stainless steel (AISI 304/316 for corrosion resistance), alloy steel (heavy-duty industrial use).
- Surface treatments: Hot-dip galvanizing, Dacromet coating, or phosphate coating for rust prevention and durability.
Manufacturing Process:
- Forging/Stamping: Forms square shape and beveled edges under high pressure.
- Machining: Precision grinding to achieve uniform bevel angles (typically 5°–15°) and flat contact surfaces.
- Heat Treatment: Stress-relieving or hardening (for alloy steel) to enhance load-bearing capacity.
- Surface Finishing: Coating application to improve corrosion resistance and reduce friction.
Key Production Considerations:
- Bevel Angle Consistency: Critical for even load distribution across bolted joints.
- Square Edge Alignment: Ensure perpendicular edges to prevent rotation during tightening.
- Thickness Uniformity: Maintain consistent material thickness to avoid uneven compression.
- Coating Adhesion: Ensure coatings withstand high clamping forces without flaking.
Applications:
- Construction: Leveling structural steel beams, columns, or base plates on uneven foundations.
- Railway Systems: Securing rail tracks or sleepers to distribute dynamic loads.
- Heavy Machinery: Aligning bolted joints in presses, cranes, or mining equipment.
- Power Transmission Towers: Stabilizing anchor bolts exposed to wind or seismic forces.
- Shipbuilding: Compensate for angular misalignment in marine structures.
Installation:
- Orientation: Place the beveled side against the nut/bolt head and the flat side against the mating surface.
- Alignment: Ensure the washer’s square edges align with the bolt head/nut to prevent rotation.
- Torque Control: Tighten gradually to allow the beveled surface to self-align and distribute pressure.
- Inspection: Verify full contact between the washer and surfaces to avoid localized stress.
Advantages:
- Anti-Rotation Design: Square shape locks the washer in place during tightening.
- Load Distribution: Beveled surfaces compensate for angular misalignment and reduce point loading.
- Durability: Robust materials and coatings withstand harsh environments.
Note:
- Avoid reusing deformed washers in critical load-bearing applications.
- Pair with high-strength bolts and nuts for optimal performance in heavy-load scenarios.
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.
