Description

AM Steel Cheese Head Slotted Screws feature a cylindrical head with a flat top and slightly rounded edge – the “cheese head” shape – paired with a traditional slotted drive for straightforward installation with a simple flat-blade screwdriver. Manufactured under the AM Steel brand to DIN 84 (with ISO 1207 as its equivalent international standard), these fully threaded machine screws are compact and low-profile, making them a common choice in electrical panels, instrument housings, nameplate fixing, and general light-duty machine assembly where a simple, reliable drive is preferred over a socket or Phillips head.

AM Steel cheese head slotted screws are available in steel (property class 4.8 and 5.8), stainless steel (A2/304 and A4/316), and brass, giving you flexibility to match strength, corrosion resistance, and conductivity needs across a wide range of applications. Brass cheese head screws are frequently specified in electrical and electronics work for their non-magnetic properties and good conductivity, while A2/A4 stainless steel versions provide reliable corrosion resistance for outdoor or washdown environments, and steel versions suit general indoor mechanical assembly.

Whether you’re wiring an electrical panel, mounting a nameplate, assembling precision instruments, or completing general light machine work, AM Steel cheese head slotted screws deliver a clean, compact fastening solution. As with all AM Steel products, this cheese head screw is available in metric sizing (M1 to M10 per DIN 84/ISO 1207), in multiple grades, materials, and finishes to suit both industrial-grade and everyday fastening needs.

Key features:

• Cylindrical “cheese head” shape with a flat top and low profile

• Manufactured to DIN 84 / ISO 1207 dimensional standards
• Available in steel (4.8/5.8), stainless steel (A2/304, A4/316), and brass
• Fully threaded for maximum engagement in thin materials
• Backed by the quality assurance of AM Steel

Ideal For

AM Steel Cheese Head Slotted Screws are ideal for:

• Electricians and panel builders using brass cheese head screws for their non-magnetic, conductive properties
• Instrument and precision equipment makers needing a compact, low-profile fastener
• Nameplate and signage installers requiring a clean, simple slotted fastening solution
• Electronics assemblers mounting components in tight enclosures where a low-profile head matters
• General light machine assembly where a straightforward slotted drive is preferred over socket or Phillips heads

Choosing the Right Cheese Head Slotted Screw

Selecting the correct cheese head screw from the AM Steel range depends on several factors:

1. Material – Brass for electrical/electronics applications requiring non-magnetic, conductive properties; stainless steel (A2/A4) for corrosion resistance; steel for general indoor mechanical use.
2. Grade – Steel property class 4.8 for general-purpose use; 5.8 for slightly higher strength requirements.
3. Size & Thread Pitch – Match the screw diameter and thread pitch (metric per DIN 84/ISO 1207, M1 to M10) to the tapped hole.
4. Drive Access – Confirm sufficient clearance and orientation for a flat-blade screwdriver, since the slotted drive has no self-centering feature.
5. Head Clearance – Verify the cheese head’s low, flat profile fits within the required enclosure or panel clearance.
6. Finish/Coating – Uncoated stainless for washdown or outdoor environments; plated steel for general indoor use where added corrosion protection is desired.

Strategies to Choose the Right Product

• Match material to the application’s electrical or environmental needs – Use brass for conductivity and non-magnetic requirements in electrical work; stainless steel for corrosion resistance; steel for general indoor mechanical assembly.
• Check grade against load requirements – Property class 5.8 offers modestly higher strength than 4.8 for applications with slightly greater mechanical demand.
• Buy in matched sets – Purchase cheese head screws with compatible nuts or ensure tapped holes match the thread pitch precisely, especially for fully threaded fine-pitch sizes.
• Prioritize certified standards – Look for DIN 84/ISO 1207 compliance for guaranteed dimensional consistency, particularly important for small sizes (M1–M3) common in electronics.
• Consider bulk vs. individual packs – Bulk packs suit electrical panel production or instrument manufacturing; smaller packs suit repairs or small assemblies.
• Verify screwdriver compatibility for automated assembly – Since slotted drives lack a centering feature, confirm your assembly process (manual or automated) can reliably locate and seat the screw without slippage.

Mechanical Properties

AM Steel Cheese Head Slotted Screws are manufactured to meet recognized mechanical and dimensional standards, ensuring reliability across electrical, instrument, and general machine assembly applications:

These mechanical ratings confirm that AM Steel cheese head slotted screws are best suited to light-to-moderate load applications where a compact profile and simple installation matter more than maximum tensile strength.

Frequently Asked Questions (FAQs)

1. What is a cheese head slotted screw used for? A cheese head slotted screw is used wherever a compact, low-profile machine screw is needed with a simple slotted drive – common in electrical panels, instrument housings, nameplates, and general light machine assembly.

2. What does “cheese head” mean? Cheese head describes the screw’s cylindrical head shape with a flat top and slightly rounded edge, resembling a wheel of cheese, distinguishing it from rounded pan heads or domed button heads.

3. Are AM Steel cheese head screws different from generic slotted screws? AM Steel cheese head slotted screws are manufactured and quality-tested under the AM Steel brand, ensuring consistent head dimensions, thread quality, and grade compliance across every batch, per DIN 84/ISO 1207.

4. What’s the difference between DIN 84 and ISO 1207? ISO 1207 is the international standard equivalent to the original German DIN 84 standard for slotted cheese head screws – the two are functionally interchangeable in dimensions and specification.

5. Why would I choose a brass cheese head screw over steel or stainless? Brass cheese head screws are commonly chosen for electrical and electronics applications due to their non-magnetic properties and good electrical conductivity, which steel and even stainless steel do not offer to the same degree.

6. Are cheese head slotted screws corrosion-resistant? Yes, especially AM Steel stainless steel cheese head screws (A2/304 or A4/316), which resist rust in outdoor, washdown, or corrosive environments; brass also offers natural corrosion resistance, while plain steel offers the least.

7. What sizes do cheese head slotted screws come in? AM Steel cheese head slotted screws are available in a range of sizes, typically M1 to M10 in metric, with lengths up to approximately 90mm, per DIN 84/ISO 1207.

8. What tools do I need to install a cheese head slotted screw? A standard flat-blade (slotted) screwdriver is used; because the slotted drive has no self-centering feature, care should be taken to keep the blade properly seated during installation to avoid slippage.

9. What grade of cheese head screw should I use? Property class 4.8 is standard for general-purpose use, while 5.8 offers modestly higher strength for applications with slightly greater mechanical demand; stainless steel grades (A2/A4) are chosen primarily for corrosion resistance rather than peak strength.

10. Are cheese head screws suitable for high-torque or structural applications? No – cheese head slotted screws are generally intended for light-to-moderate load, precision, and electrical applications rather than high-torque or structural fastening, where a socket head cap screw or hex bolt would be more appropriate.

11. Can cheese head slotted screws be reused? Yes, as long as the threads and slot aren’t damaged, stripped, or worn, cheese head slotted screws can typically be reused in non-critical applications.

12. What’s the difference between A2 and A4 stainless steel cheese head screws? A2 (304) stainless offers good general corrosion resistance for most indoor and outdoor use, while A4 (316) stainless provides superior resistance to chlorides and marine or washdown environments.

13. Is a cheese head screw fully threaded? Yes, standard DIN 84/ISO 1207 cheese head slotted screws are fully threaded from just below the head to the tip, maximizing thread engagement, particularly useful in thin materials.
