Recision Original New Robot Protection Screw ABB 3HAC14024-1 indispensable Spare Part Accessory

ABB Robot Protection Screw 3HAC14024-1 – OEM Fastener for Industrial Robots

The ABB Robot Protection Screw 3HAC14024-1 is an original ABB fastener engineered for securing protective components, covers and cable protection hardware on multiple ABB industrial robot families such as IRB 660, IRB 6620 and IRB 6660. In ABB spare parts documentation it is clearly identified as a “Protection screw”, used where reliable fastening and long-term mechanical stability are required around axis-1, base assemblies and SMB/cable protection areas. 

This screw is designed to match ABB’s mechanical standards for head type, thread, strength class and corrosion resistance, making it an ideal replacement part during robot maintenance, refurbishment or on-site service.

Technical Specifications – ABB 3HAC14024-1

1. Product Overview

ABB Robot Protection Screw 3HAC14024-1 is a genuine OEM fastener used to hold protective elements and mechanical accessories in place on ABB articulated robots. In several ABB product and spare-parts manuals it appears as a dedicated line item, confirming its role as a defined protection screw rather than a generic hardware store bolt. 

The screw is typically found in critical regions such as:

• Base and axis-1 framings and covers

• Synchronization plates and mechanical stops

• Cable protection assemblies and SMB (Serial Measurement Board) mounting areas

Because these zones experience vibration, load transfer and frequent movement, the choice of a high-strength M6 Torx screw with controlled quality is important for maintaining structural integrity and protecting cables, measuring electronics and mechanical stops over the full lifetime of the robot. 

2. Technical Characteristics

Although small, the 3HAC14024-1 protection screw incorporates several technical features that make it suitable for demanding industrial automation environments:

Thread and geometry

• Metric M6 thread, compatible with ABB robot frames, covers and brackets

• Typical length around 20 mm, enough to engage adequately in the mating component without interfering with moving parts 

Head style

• Torx pan head configuration allows secure torque transfer from the tool to the fastener

• Torx drive reduces the risk of cam-out compared with conventional Phillips or slotted heads, which is useful when working inside robot bases and tight enclosures

Strength and material quality

• Classified as 8.8 quality, consistent with high-strength carbon steel structural screws, offering reliable tensile and shear performance in dynamic applications 

• A2F quality designation in the ABB documentation refers to surface treatment and fastener quality suitable for industrial use and improved corrosion resistance

Low mass, high reliability

• The screw adds negligible mass to the robot structure while ensuring that covers, plates and protective hardware remain firmly clamped, even during high-speed motion cycles

3. Function in ABB Robot Systems

In ABB spare-parts lists for robots such as the IRB 6660, the 3HAC14024-1 appears together with mechanical stop assemblies, frames and protection covers, confirming that its primary role is protection rather than structural load-bearing in the main kinematic chain. 

Typical functions include:

1. Securing protection covers

   • Fixing protective covers around axis-1 mechanical stops or base areas

   • Preventing ingress of dust and debris into sensitive mechanics or lubrication zones

2. Cable and SMB protection

   • Holding cable protection parts and plates near the SMB, as shown in IRB 6620LX documentation where the screw is listed together with cable protection and a dedicated washer and nut. 

   • Ensuring that feedback and measurement cables remain correctly retained and shielded from mechanical damage

3. Alignment of secondary components

   • Fastening synchronization plates or accessory brackets, helping keep these parts in the designed position so that robot calibration and mechanical stops function correctly. 

By fulfilling these roles, the protection screw contributes indirectly but significantly to robot uptime, stable accuracy and reduced risk of unplanned stops caused by loose covers or damaged cabling.

4. Key Features and Advantages

Original ABB specification
Being an ABB-defined part number instead of a generic screw means its geometry, material and coating have been selected to meet the company’s internal standards for robotics applications. 

Robust under industrial conditions
The 8.8 strength class and Torx head allow the screw to withstand constant vibration, dynamic loading and repeated service interventions, which are typical in multi-shift production lines. 

Improved serviceability
Using a known, documented part number simplifies maintenance:

• Field technicians can quickly identify the correct screw in ABB spare-parts manuals. 

• Replacement is straightforward because no adaptation of threads or lengths is required.

Corrosion resistance and long life
The quality designation (including A2F type information) reflects a surface treatment suited for industrial environments, helping maintain clamping force over time and reducing the risk of seized fasteners during future service work. 

Cost-effective protection
Using the proper protection screw is a minor cost compared with potential damage to cables, SMB units or mechanical stops if covers or protection elements loosen during operation.

5. Typical Applications and Robot Models

The ABB 3HAC14024-1 protection screw appears in documentation for several robot families:

• IRB 660 palletizing robots – used around base and linkage assemblies, where protective covers and plates surround axis-1 mechanics. 

• IRB 6620 and 6620LX – listed in complete robot spare-parts sections and near SMB/cable protection assemblies. 

• Other IRB models in the same mechanical platform family, where compatible base frames or protection kits share the same screw specification.

Across these robots, typical application scenarios include:

• General industrial handling and machine tending

• Heavy-duty applications such as forging or press tending (IRB 6660 family)

• Palletizing and logistics systems requiring continuous operation

6. Installation and Maintenance Guidelines

When installing or replacing ABB Robot Protection Screw 3HAC14024-1, technicians should follow the mechanical and safety instructions in the specific robot’s product and service manuals: 

• Confirm the location and quantity of 3HAC14024-1 screws required in the assembly diagram.

• Inspect mating components (covers, cable protections, plates, washers and nuts) for wear, deformation or corrosion.

• Clean the contact surfaces, removing dirt, old sealant or corrosion products.

• Use the recommended tightening torque for M6 fasteners in ABB robots, following the table in the manual; this ensures sufficient clamping force without overstressing the screw.

• Where specified, combine the screw with the correct ABB washer and nut part numbers, for example 3HAC17423-1 washer and 9ADA269-4 nut in SMB/cable protection assemblies. 

Regular inspection of protection screws during preventive maintenance can help detect early loosening or environmental damage before it affects cables, measurement devices or protective covers.
