Description
Overview:
The Sealey Threaded Insert (Rivet Nut) M4 Splined - TISM4 is a zinc‐plated steel insert for adding strong, reusable threads to thin or hollow sections where tapping is not possible. The splined shank bites into the parent material to resist spinning under load, helping create secure fixings in sheet steel, aluminium, and certain plastics. Fitted with a rivet nut tool, it can be installed from one side (blind installation) without access to the rear of the workpiece. Supplied in a pack of 50 for workshop, site, or maintenance use, these M4 inserts suit tasks on vehicles, machinery panels, cabinets, frames, and fixtures. The durable zinc plating provides corrosion resistance for indoor and outdoor applications, supporting reliable, repeatable assemblies.
Key Features:
- M4 metric thread for common fastenings in light fabrication and repair
- Splined body for enhanced torque resistance and anti‐rotation in sheet materials
- Zinc‐plated steel construction for durability and corrosion resistance
- Blind installation from one side, ideal where rear access is restricted
- Consistent sizing for repeatable results across production runs and repairs
- Compatible with most hand, cordless, and pneumatic rivet nut setters that accept M4 inserts
- Flanged rim helps spread load and reduce pull‐through on thin sheet
- Pack of 50 provides ample stock for workshop and site jobs
- Suitable for steel, aluminium, and some plastics when used with the correct tool and setting force
- Neat, professional finish with a reusable machine thread for bolts and screws
Typical Applications:
Creating threaded anchor points in automotive bodywork, machinery guards, electrical enclosures, racking, HVAC ducting, signage, metal furniture, trailers, and garden or construction equipment panels. Useful for mounting brackets, clips, hinges, and accessories where thin material prevents conventional tapping. Ideal for repairs, retrofits, and light fabrication.
