What are Blasting Plugs?

Blasting Plugs are specialised engineering components designed to serve as a robust barrier against contaminants during shot blasting and wet painting applications. This ingenious invention prevents abrasive grit or liquids from compromising the quality of threaded entries, ensuring a pristine finish in your precision engineering tasks. Accu's blasting plugs are also equipped with a slotted drive, offering easy installation and removal with the simple turn of a screwdriver.

How Blasting Plugs Work.

The operational principle of blasting plugs is fundamentally focused on barrier formation. Inserted into threaded holes, these plugs effectively seal the orifice against any external agents like shot blasting grit or wet paint. The slotted drive ensures the plug can be easily screwed in or removed, offering both stability and ease of use. Moreover, the sealing capability of the sand blasting plugs is optimised to function in a wide temperature range, from -30°C to 50°, granting them a dynamic application scope.

What Material Blasting Plugs Are Made From.

Comprising Low-Density Polyethylene (LDPE), shot blasting plugs offer a unique blend of durability, flexibility, and chemical resistance. LDPE is renowned for its exceptional insulating properties and low water absorption rate, making it ideal for both shot blasting and wet painting applications. The red colour of these plugs adds an additional layer of visual identification, simplifying the process of spotting and removing them post-application.

What Size and Type Blasting Plugs Are Available.

Accu offers blasting plugs in various sizes to meet the specific demands of your precision engineering tasks. While primarily designed for standard metric dimensions, custom sizes can also be catered to. Furthermore, for applications requiring a different material or colour, we offer customisation services to tailor the blasting plugs to your unique requirements.

If you find the features of blasting plugs beneficial, you might also be interested in our range of silicone masking plugs which are designed to withstand harsher abrasive materials and temperatures.


Q: How do blasting plugs differ from blast hole plugs?.

A: While both blasting plugs and blast hole plugs are designed to seal orifices, blasting plugs are specifically engineered for threaded holes and can withstand both shot blasting and wet painting applications.

Q: Are blasting plugs resistant to chemicals?.

A: Yes, made from Low-Density Polyethylene, our blasting plugs offer good chemical resistance, making them suitable for use in wet painting applications.

Q: What tools are needed to install or remove blasting plugs?.

A: A standard screwdriver with a slotted drive is all you need for quick and easy installation or removal of our blasting plugs.

Q: How do I choose the right size for my blasting plug?.

A: Selecting the correct size of the blasting plug depends on the dimensions of the threaded hole you are working with. Accu offers a range of sizes to cater to various engineering needs.

Q: Is there a minimum order quantity for blasting plugs?.

A: No, at Accu, we understand the diverse needs of our clients. You have the flexibility to order as little as one unit or as many as you need for your project.
