Tapping and countersinking
Do you want a perfectly finished product? Then De Cromvoirtse is the place to be! You may want even more added value after the operations we can perform for you in-house. We are therefore happy to provide further finishing touches to your product. Using professional equipment, we take care of your tapped holes in the laser-cut products. Beforehand, the holes are countersunk according to the applicable standard, after which metric threads are fitted in accordance with the drawing. If the hole only needs to be countersunk, the appropriate tools are available and this is also done in accordance with the drawing.
Engineered nuts
Draw-in nuts (also called blind rivet nuts) consist of a tubular/hollow front part that allows a nut to be fixed in a hole without touching the back of the product. The advantage of this is that only one side of the product needs to be accessible. Due to the large surface area of the nut on the blind side, this ensures a strong and durable connection. And by precise positioning, we ensure that the end product will look the way you envisage it.
Another great advantage of engineered nuts compared to blind rivets is that the products being joined can also be dismantled.
Press-in threaded
Making an attractive connection in exactly the right position that is also strong and durable, especially in thin sheet material.
Compact and reliable, in exactly the place you specify! We gladly think along with you to produce workpieces even more efficiently!
- Perfectly finished product
- Saving time & money
Stud-welded bolts
This fastening technique in which metal studs (threaded ends) are welded onto sheet metal is often used for thin sheet metal housings, e.g. in equipment construction.
Studs with an external threaded end can be fitted to the inside of a sheet metal housing. In this way, various machine components can be attached to the inside of the enclosure.
Because of little or no discolouration and deformation to the material, little or no post-processing is also required. Because it is suitable for various types of material and for thin sheets in particular, this post-processing offers great added value.
Flow drilling
Through friction, threaded bushings are formed in thin sheet material. A combination of speed and pressure force creates frictional heat. This can reach up to 700° for the material. The softened material is pushed away, creating both a bore and a threaded bushing from the displaced material.
