Slotted Cheese Head Machine Screw DIN 84 Steel Stainless Steel and Brass Fastener for Equipment Panels and General Assembly

DIN 84 Slotted Cheese Head Machine Screws combine a cylindrical head with a single straight slot for installation using a flat-blade screwdriver. The head remains above the mounting surface, while the machine thread connects to a compatible tapped hole or matching nut.

The cylindrical head provides a defined bearing surface and an accessible drive for assembly and removal. This product form can be selected for equipment panels, covers, instruments and general mechanical assemblies designed for slotted machine screws.

The DIN 84:1990 reference includes thread diameters from M1 to M10. Material, mechanical properties, screw length and surface treatment should be specified together so the quotation follows the required configuration.

Product Specifications

The listed dimensions and material classes are standard reference information. Availability is determined for the requested material, diameter, length, property class and surface treatment combination.

Material and Mechanical Requirements

Material designation, mechanical property class and product grade describe different requirements. Product Grade A refers to dimensional tolerances, while designations such as 4.8, 8.8 and A2-70 describe mechanical properties.

For an inquiry, identify the required material and property class separately. Where a particular alloy or copper-alloy condition is required, include the designation on the drawing or purchase specification.

Cylindrical Head and Slotted Drive

The cylindrical head sits above the component surface. Head diameter and head height are therefore important when checking clearance around covers, brackets and adjacent parts.

The straight slot provides access for a flat-blade screwdriver. A correctly fitting blade helps maintain engagement with the slot during installation and removal. The surrounding assembly should provide sufficient space to keep the driver aligned with the screw.

For replacement purchases, compare the head diameter, head height, slot dimensions and thread specification. Similar appearance alone does not establish that another screw type will fit the assembly.

Screw Length and Shank Configuration

The nominal length of a DIN 84 cheese head screw is measured from the bearing surface beneath the head to the tip. The head height is excluded from this measurement.

Specify the diameter and nominal length together, for example M4 × 12, and list the required thread length separately when the assembly calls for a partially threaded configuration.

The standard reference allows the unthreaded shank diameter to correspond to the thread major diameter or approximately to the thread pitch diameter. Where shank diameter affects alignment or fit, identify the required dimension in the drawing.

Applications

DIN 84 slotted cheese head machine screws can be considered for assemblies designed with compatible internal threads or matching nuts, including:

Equipment panels and removable covers.

Instrument housings and small mechanical assemblies.

Brackets and hardware with clearance for a cylindrical head.

General assembly requiring a straight-slot drive.

Replacement parts specified by standard and drawing.

The screw uses a machine thread. Applications involving unthreaded sheet metal, wood or plastic require an appropriately designed threaded connection, insert or nut.

Related Standards

DIN 84:1990 is associated with standards including ISO 1207, DIN EN ISO 1207, GB/T 65, UNI 6107 and NF E 25-127.

Related standards may have dimensional or technical differences. State the required standard and edition in the inquiry, particularly when replacing an existing fastener or working with restricted head clearance. Alternative standards should be checked against the assembly drawing before substitution.

Information Needed for a Quotation

Provide the following details for each item:

Standard reference and edition.

Thread diameter and pitch.

Nominal screw length and required thread length.

Material designation and mechanical property class.

Required surface treatment.

Quantity for each specification.

Critical dimensions and assembly drawing, where applicable.

Inspection, packaging and delivery requirements.

For replacement orders, a dimensioned drawing or clearly identified sample can help define the head, thread and shank requirements.

FAQ

1.What is a DIN 84 screw?

DIN 84 is a slotted cheese head machine screw with a cylindrical head and a metric machine thread. The standard reference used here is DIN 84:1990.

2.Does the nominal length include the head?

No. Nominal length is measured from under the head to the screw tip.

3.What does Product Grade A mean?

Product Grade A describes dimensional tolerances. It is separate from the material designation and mechanical property class.

4.Which materials are included in the reference?

The reference includes steel, stainless steel and copper-zinc alloy. Steel property classes include 4.8, 5.8 and 8.8. Stainless steel references include A2-70 and A4-70. The required combination should be stated with the inquiry.

5.Can DIN 84 be replaced with ISO 1207?

The standards are related, but substitution requires checking the applicable dimensions and technical requirements. Specify the controlling standard and edition on the order.

6.What should I send for a quotation?

Send the standard, diameter, pitch, nominal length, material, property class, finish and quantity. Include a drawing when head clearance, shank dimensions or thread length are critical.
