Key features

Heavy-Duty Clamping Force: Trapezoidal thread screw generates 2000-2500 N force with hand tightening, up to 3500 N with hex key.

Durable Heat-Treated Material: Made from 45# medium carbon steel heat-treated to HRC 38-42, with screw hardened to HRC 50-55.

Anti-Spatter Surface Finish: Black oxide or zinc-plated surface ensures easy slag removal and resistance to welding spatter.

Universal Table Compatibility: Fits standard 28mm table bore holes and common grid patterns like 50x50mm or 100x100mm.

Customization Available: Accepts customized orders for material (e.g., SS304), angles, and finishes upon request.

Fast Stock Delivery: Lead time is 7-15 days for stock items and 25-30 days for bulk OEM orders.

Stable Locking Mechanism: Screw mechanism locks tighter than cam-style clamps, preventing walking due to weld shrinkage.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company and professional technical supplier offering 3D software design and design-based customization. It provides OEM services for well-known brands, but does not offer ODM services or an SDK, and reported no new products during the past year. Evidence indicates CCC and ISO9001 certification for most products, domestic sales across more than 20 provinces and exports to over 30 countries. Customer complaint handling has a clear procedure with follow-up records, while no written corrective and preventive action procedures were found. Overseas service infrastructure is limited, with no overseas showroom, agents, branches, or offline trade-show participation. Digitalization is undeveloped, with no ERP, OA, CRM, SAP, or big-data implementation reported. Production capacity is not directly established because the company is classified as a trading company and manufacturing scale data is absent.

CertificationsThe company description states that most products have passed China National CCC certification and ISO9001 international quality system certification. The evidence supports certification coverage for most products, but not necessarily every product.

R&D capabilityThe supplier has one R&D engineer and provides design-based customization, but reported no new products in the past year. It also does not provide ODM services or an SDK, indicating limited demonstrated product innovation.

Customization capabilityThe supplier explicitly provides customization from designs and offers 3D software design services. This directly supports design-led customization capability, although the absence of ODM service limits the broader development scope.

Client casesThe supplier states that it provides OEM services for well-known brands and that its products sell in more than 20 Chinese provinces and cities and are exported to over 30 countries. These statements provide evidence of customer and market experience, although specific customer names or case details are not supplied.

Product Q&A

Q:How much clamping force does the screw tightener provide?

The trapezoidal thread screw generates approximately 2000-2500 N (450-560 lbs) of clamping force with hand tightening. Using a hex key (on models with a hex drive) can increase this up to 3500 N, but we recommend staying within hand-tight ranges to avoid thread damage.

Q:What material is the clamp made of? Is it heat-treated?

Standard models are made of 45# medium carbon steel, heat-treated to HRC 38-42 for wear resistance. The screw is case-hardened to HRC 50-55. For corrosive environments (stainless steel welding, marine applications), we offer SS304 stainless steel versions.

Q:Can this clamp hold round pipe as well as square tube?

Yes. The serrated clamping plate grips round surfaces effectively. For best results with small-diameter pipe (under 20mm), we recommend our V-pad accessory (available separately).

Q:What payment methods do you accept?

T/T (bank transfer), L/C, PayPal (for samples), and Western Union. For first-time orders, we typically require 30% deposit and 70% before shipment.
