Made from customer drawings, custom-made fasteners respond to specific applications. These fasteners use different manufacturing processes – bar turning, cold heading, hot forging, etc. –, which require proven technical expertise and state-of-the-art equipment. HEATSCREW realizes according to the plans or the specifications of the customer of the parts of screws and bolts to measure.
The advantages of using a manufacturer
When the screws you need for your mechanical system or your construction cannot be found on the market, the best option to obtain these types of parts is to hire a manufacturer. The latter can design and manufacture your custom fasteners. He can even, if necessary, help you identify your needs, including the appropriate size and type of screws.
He can also choose the material, metal or alloy, in which your screws will be cut in order to meet the performance and safety requirements. If you need screws for industrial use or for specific environments such as those intended for nuclear islands, he will manufacture them in accordance with the standards imposed by the legislation.
However, when choosing your provider, it is recommended to rely on the experience and reputation of the latter to ensure that you will ultimately have quality parts. In addition, we have a large stock of raw materials from which your set of screws will be made to measure. The professionals with whom we collaborate give us the possibility of storing several raw materials such as: alloy steel, Monel, Inconel, stainless steel, cupro-aluminum or even bronze, etc.
The techniques used for the realization of custom screws
To meet the requirements of our customers, we offer various processes for the production of special parts. Thus, depending on the plan drawn up by the sponsor, we can opt for hot forging, threading by cold rolling, cutting, turning, milling, etc.
It goes without saying that the choice of materials, dimensions and lengths as well as the heat and surface treatments to be applied to the parts is up to you. Nevertheless, our design office accompanies you during the screw study and design phase in order to propose improvements and innovative technical solutions, if necessary.
The manufacture of custom screws and bolts requires several parameters to be defined upstream: the material intended to accommodate the screw, the thickness and resistance of the support, the material of the screw or the tearing and shear stresses.
From these elements, the manufacturer can then determine the appropriate manufacturing process.
In this regard, there are two main methods: manufacturing without chip removal, which itself includes the cold stamping process and the hot stamping process, and bar turning.
HEATSCREW uses bar turning to manufacture very small parts or parts with complex shapes.
On the other hand, for the screws of large series and having a diameter of 2 to 24, the manufacture is done by cold stamping.
On behalf of a wide variety of industries, we are regularly called upon to machine special screws and bolts according to a precise plan or model.
Our service offer is aimed at players in all sectors of activity
Our area of ​​expertise is not limited to the security screw manufacturer. Offering our services to manufacturers in different sectors of activity (nuclear, armaments, transport, energy, cement works, petrochemicals, etc.), we can also take charge of the production of safety and wear parts, rocker ball joints, turned parts and dowels.
You can even ask us to produce mechanical parts in small series for special machines or to assemble specific mechanical assemblies or sub-assemblies. The products are of course subjected to a battery of specific tests and to destructive and non-destructive checks before being delivered by us.
To guarantee the conformity of the parts produced with the quality standards and the specifications, we can, at your request, manufacture prototypes before the launch of production.
As soon as the order form is signed, we take care of all the operations that are already planned so that your order is delivered to you on time.
