Master 501278 Clip-on Steel Anchor 20×150 mm

Master 501278 Clip Steel Anchor 20x150 mm

Structural Beyond Strength for Ultra-Heavy and Critical Loads

Master 501278 Clip Steel Anchor 20x150 mm is an ultra-super heavy-duty (Mega Heavy-Duty) anchor designed for fixing the heaviest, most dynamic, and most critical non-structural industrial and structural loads to solid concrete or natural stone surfaces with the highest industrial-grade strength, deep anchorage, and absolute reliability. With a 20 mm diameter, it offers the highest tensile and shear resistance values achievable in the clip anchor family, while its 150 mm (15 cm) length ensures secure attachment to the main structure by penetrating very thick mounting plates and surface layers.

This anchor is made of high-strength, critical service steel that expands as the nut is torqued, locking immovably into the main structural material. Thanks to its clip/wedge anchor design, as the nut is tightened, it pulls the clip beneath it upwards, providing a structural lock at the bottom of the hole. Its immense 20 mm thickness and 150 mm length make it unrivaled for applications requiring heavy vibrating machine bases, seismic supports, and a high safety margin.

Areas of Use and Industries

Master 501278 Clip Steel Anchor 20x150 mm is a fundamental component, especially in heavy industry, energy, and large infrastructure sectors, thanks to its highest load-bearing capacity, deep anchorage, and critical safety requirements:

Sectors

Heavy Industry and Machine Assembly (Critical): Securing high-vibration and dynamically loaded equipment such as large industrial presses, CNC machines, heavy pump and motor bases to the floor.

Energy and Petrochemical Facilities: Anchoring the largest and heaviest main pipelines, reactor supports, and non-structural legs of electrical transformers in refineries, natural gas compressor stations, and power plants.

Infrastructure and Bridges: Critical installation of expansion joint rebar, thick seismic dampers, and heavy steel safety barriers in bridges and viaducts.

Steel Construction (Heavy Supports): Installation of non-structural but heavy-load bearing thick steel column bases (e.g., 30-40 mm thick base plates) and large steel cantilevers to the floor or wall.

Storage and Logistics: Floor anchoring of main support legs for multi-story and ultra-heavy load-bearing, automated warehouse systems.

Applications

Maximum Load Capacity: The 20 mm diameter offers the highest tensile, shear, and bending resistances provided by clip anchor technology, ensuring a high safety factor for the most demanding industrial loads.

Resistance to Dynamic Loads: The 20 mm wide and deep locking created by the clip design prevents the anchor from loosening under high-vibration machine loads, ensuring long-term operational safety.

Thick Mounting Parts: The 150 mm length guarantees that very thick (30-50 mm) steel mounting plates are securely anchored to the main structure with sufficient and safe anchorage depth.

Deep Anchorage Security: Even in cases with thick screed, epoxy, or damaged surface layers, the 150 mm length ensures that the anchor holds in the structurally soundest core region of the concrete.

About the Product 20x150 mm Clip Anchor: The Industrial Symbol of Strength and Depth

20 mm Diameter: Definition of Raw Power

In the world of anchoring, 20 mm (M20) diameter is the starting point for ultra-heavy-duty and critical safety applications. Master 501278 Clip Steel Anchor 20x150 mm combines the maximum strength a clip anchor of this diameter can offer with its clip design. This anchor demonstrates unique resistance to fatigue caused by dynamic loads, such as those from industrial presses and vibrating motors, as well as static loads. Its ability to achieve high torque values during installation creates an unshakeable pretension within the concrete, ensuring the safety of the most critical connections.

150 mm Length: Thick Mounting and Deep Security

The anchor's 150 mm length complements the strength provided by the 20 mm diameter with deep anchorage security. Modern industrial facilities often use thick steel plates and infill materials to reduce vibration or adjust height. This length ensures that the bolt portion of the anchor is sufficiently and securely embedded in the main structure, even when thick mounting parts are used. In other words, 150 mm guarantees that the 20 mm strength will be fully activated in the main concrete regardless of the mounting thickness.

Flexibility in Critical Industrial Environments

Master 501278 offers speed and reliability in a single product. It significantly shortens installation time compared to complex and time-consuming chemical anchoring methods, especially on dry and hard surfaces. Its high-strength steel material ensures that the anchor withstands corrosion and harsh operating conditions in the long term. This anchor is the ultimate and indispensable fastener for all critical industrial and infrastructure applications involving overload, vibration, and thick mounting parts.

Master 501278 Clip Steel Anchor 20x150 mm, thanks to the highest load capacity achievable with a 20 mm diameter, the critical deep anchorage security provided by its 150 mm length, and the unshakeable dynamic grip of its clip design, is a high-performance, specialized, and essential fastener for the deepest and most reliable anchoring of ultra-heavy and critical loads in heavy industry, energy, machine assembly, infrastructure, and steel construction sectors.
