Professional nut serts for commercial or occasional use. This pack contains 25 M8 nut serts, suita...Professional nut serts for commercial or occasional use. This pack contains 25 M8 nut serts, suitable for use with most materials that cannot be tapped or welded. The dual-action nut sert can be used as blind fasteners or screw anchors. Aluminium nut serts will not rust or corrode and provide a strong thread in thin materials that cannot be tapped. Requires access to only one side of the workpiece. The nut can be installed after painting or other finishing operations to provide a robust screw anchor, eliminating problems of welding and material distortion. Once installed, they are permanently attached to the mating material, allowing the associated nut to be removed in service without risk of the fastener becoming dislodged. Features strong threads (at least 6 turns, even on thinner materials), serrations/grooves on the body to help prevent rotation, and a large flange that reinforces the hole in thin materials and increases pull-out resistance. Suitable for use with most nut sert tools.
SPECIFICATIONS:
• Thread diameter - 8mm
• Sleeve inner diameter - 8mm
• Sleeve outer diameter - 15mm
• Pack size - 25pc.

This guide is for professionals and DIY enthusiasts needing secure fastening solutions in materials that cannot be tapped or welded. The AB Tools M8 Nut Serts provide a strong, rust-proof thread in thin materials, offering a robust alternative to traditional methods. A key benefit is their ability to be installed after painting, preventing distortion and damage. However, users must ensure they have a compatible nut sert tool for installation.

FAQs
What materials can these nut serts be used with?
They are suitable for a wide range of materials including aluminum, steel, plastic, and composites, provided they are not too thin to provide sufficient grip for the nut sert's body and flange.
Do I need a special tool to install these?
Yes, you will need a nut sert tool (also known as a rivet nut tool or rivnut tool) that is compatible with M8 sized nut serts.
Can these nut serts be used in outdoor applications?
Yes, as they are made of aluminum, they are resistant to rust and corrosion, making them suitable for outdoor and marine environments.
What is the minimum material thickness recommended?
While specific minimums depend on the material's strength, the nut sert is designed to provide at least 6 turns of thread. It's best to test on a scrap piece of your material to ensure adequate grip and pull-out strength.
Can I remove the bolt after the nut sert is installed?
Yes, once installed, the nut sert provides a permanent threaded anchor. You can remove and reinsert the bolt multiple times without damaging the nut sert or the surrounding material.
Are these nut serts suitable for structural applications?
They provide strong threads suitable for many applications. For critical structural joints requiring very high load-bearing capacity, it's advisable to consult engineering specifications or consider larger fasteners.
How do the serrations help?
The serrations or grooves on the body of the nut sert help to grip the material and prevent the nut sert from spinning or loosening under vibration or load once it is installed.
Troubleshooting
Nut sert spins after installation
Ensure the serrations on the nut sert body are fully engaged with the material. Check that the drilled hole is the correct size and that the material is not too thin or soft. Reinstall with firm pressure.
Nut sert tool not deforming the nut sert properly
Verify that the tool is set to the correct size for M8 nut serts. Check the tool's mandrel for wear or damage. Ensure the nut sert is fully seated in the tool before operation.
Thread cross-threading during bolt insertion
Ensure you are using the correct M8 bolt and that it is aligned properly with the nut sert's internal thread. Avoid forcing the bolt; if resistance is met, back it out and try again.
Nut sert body cracks during installation
This may indicate excessive force or the material being too brittle. Reduce the force applied by the nut sert tool. Ensure the hole diameter is correct for the nut sert sleeve.
Pros and Cons
Pros
Prevents rust and corrosion due to aluminium construction.
Ideal for thin materials where traditional tapping is not feasible.
Allows for installation after painting, protecting finishes.
Minimizes risk of material distortion compared to welding.
Provides a secure, non-rotating anchor point.
Suitable for blind applications where access is limited.
Cons
Requires a specific nut sert tool for proper installation.
Limited to M8 thread size.
May not be suitable for extremely heavy-duty structural applications.
A pack contains only 25 pieces, which may require multiple purchases for large projects.
Setup, Compatibility & Care
Setup:
Select the Correct Tool: Ensure you have a compatible nut sert tool sized for M8 rivets.
Drill Hole: Drill a hole in your workpiece with the appropriate diameter for an M8 nut sert (typically around 15mm for the sleeve outer diameter).
Insert Nut Sert: Place the nut sert into the drilled hole, ensuring it is seated correctly.
Engage Tool: Load the nut sert into your tool and engage the mandrel with the internal thread.
Install: Operate the nut sert tool according to its instructions to deform the nut sert sleeve and create a permanent anchor.
Compatibility:
Thread Size: Compatible with M8 bolts and screws.
Material Thickness: Suitable for a wide range of material thicknesses where at least 6 thread turns can be achieved.
Tools: Requires a manual or pneumatic nut sert tool designed for M8 applications.
Care:
Cleaning: Clean with a damp cloth. Avoid abrasive cleaners that could damage the finish.
Storage: Store in a dry place to prevent any potential corrosion, although aluminium is highly resistant.
Inspection: Periodically inspect installed nut serts for any signs of loosening or damage, especially in high-vibration environments.
