DIN 914 Set Screw with Cone Point

Standard DIN 914 defines a set screw with a cone point and an internal hex socket. This is a special fastening element designed for secure fixation of parts relative to one another: it is used to join parts made of any metals and alloys.

It looks like a rod with full metric thread, has no head and is fully recessed into a drilled hole in the material. The special socket ensures reliable driving with high tightening torque.

Purpose and manufacturing features

In appearance, this fastener resembles a threaded stud fitted with a hex socket, with one end pointed. This shape is the optimal solution for installation into a drilled hole in the material, which must be pre-tapped with a matching thread pitch.

Screws of this type are used for a secure connection between parts and to prevent their axial displacement. Such fasteners are needed for fixing the parts of assemblies that are subject to constant dynamic loads and vibration. The use of set screws prevents deviations from occurring during operation; the significant force applied when tightening the fastener gives the joint high strength.

For ease of installation, the product is fitted with a sharp cone point, which fixes most reliably in the material. The screws can be used to join parts made of any kind of metal, as well as plastic, wood, and more. DIN 914 fastener products can have a thread diameter from M6 to M16, and a length from 3 to 50 mm depending on the application. Similar products are manufactured to GOST 28964 and ISO 4029, though these may include minor deviations.

Materials used in manufacturing fasteners

The most common material for manufacturing is 45H steel, which has a high level of strength. The screws can be left uncoated or fitted with white or yellow galvanic zinc plating. The zinc layer provides enhanced corrosion protection: it withstands prolonged contact with moisture or significant temperature fluctuations.

Set screws can also be manufactured from A2 and A4 stainless steels — these alloys contain additional chemical elements that resist corrosion. Such materials are used to produce screws intended for use in environments with constantly high corrosive activity.

Fastener products are also manufactured from brass or polyamide. These materials are not subject to corrosion, so they can be used where steel with any coating would quickly deteriorate. Polyamide products do not have high strength, so they are used for unloaded connections.

Application possibilities for fastener products

Screws manufactured to DIN 914 can be used in various industries. They are applied in mechanical and instrument engineering; set screw products are used in the assembly of production machinery, engines, and various metal structures. They can also be used in construction for assembling metal frames, and are applied in automotive manufacturing, furniture production, and more.

Since the fastener has no head, it is fully recessed into the material and the fastening point is not visible from the outside. This is important for furniture production and the manufacture of various household items: fasteners with a hex socket are fully concealed within the material.

The set screw with a cone point provides secure fixation in the material — this is what makes it so widely applicable.
