Metric Slotted Cheese Head Screws.

What are Metric Slotted Cheese Head Screws?

Slotted cheese head screws are precision-engineered fasteners designed with a cylindrical 'cheese-wheel shaped' head profile and a slotted drive, making them ideal for controlled torque applications.

Their uniform head shape allows even pressure distribution during installation, reducing the risk of surface damage or deformation. Commonly used in engineering assemblies, instrumentation and electrical enclosures, these screws offer a dependable fastening solution where repeatability, even load distribution and drive compatibility are essential.

How Slotted Cheese Head Machine Screws Work

These slotted cheese head machine screws are tightened using a flat-blade screwdriver, with torque transferred through the slot into the screw’s metric machine threads for a secure, vibration-resistant fit.

The broad head design enables precise torque control and spreads the clamping force evenly, protecting surfaces from damage and ensuring reliable, repeatable fastening. Their metric machine threads provide a secure, vibration-resistant fit in tapped holes or paired with corresponding nuts in through-hole applications.

Materials Slotted Cheese Head Screws Are Made From

Our wide selection of engineering material options are perfectly tailored for different environments and mechanical requirements. For example, brass cheese head screws, chosen for their aesthetic appeal, or stainless steel cheese head screws, valued for their corrosion resistance.

• Steel - (4.8): A versatile option for general-purpose applications.
• Stainless Steel - (A2): Provides excellent corrosion resistance for indoor or mildly corrosive environments.
• Stainless Steel - Marine (A4): Ideal for use in marine, chemical or other highly corrosive environments.
• Plastic - PVDF: Offers chemical resistance and thermal stability, suitable for specialised industrial uses.
• Plastic - PP: Lightweight and non-conductive, ideal for use in moisture-sensitive assemblies.
• Plastic - Nylon: Combines strength and flexibility with electrical insulation properties.
• Ceramic: Inherently non-conductive and heat-resistant, suitable for extremely high-temperature applications.
• Brass: Corrosion-resistant and electrically conductive, frequently used in electrical or decorative components.

Sizes and Types of Slotted Cheese Head Screws Available

Accu's range of metric cheese head screws includes a comprehensive range of sizing and finish options:

• Thread Sizes: From M0.5 (0.5 mm) to M16 (16 mm)
• Lengths: From 2 mm up to 100 mm
• Finishes Available: Zinc plating provides cost-effective corrosion protection, while silver plating offers excellent conductivity for electrical applications. AccuBlack delivers a sleek, non-reflective finish and AccuLock adds a thread-locking feature to prevent loosening under vibration.

These variations ensure compatibility across light and heavy-duty assemblies, providing engineers with reliable options for prototyping, repair or production use.

FAQs

Q: Why is it called a cheese head screw?

A: The term refers to the cylindrical shape of the head, which resembles a wheel of cheese. This head profile offers a broad bearing surface and clean appearance compared to other types of screw heads.

Q: What’s the difference between a cheese head screw and a pan head screw?

A: Cheese head screws have a more angular profile with vertical sides, while pan head screws are rounded and lower in profile. Cheese heads typically provide a larger surface contact area.

Q: Can slotted cheese head screws be used with power tools?

A: Yes, though care should be taken to avoid cam-out or over-torquing. Precision torque control tools are recommended.

Q: Which material is best for corrosion resistance?

A: Stainless Steel - Marine (A4) provides the highest resistance to corrosion, especially in saltwater or chemical environments.

Q: Are slotted cheese head screws suitable for use in plastic housings?

A: Yes, particularly those made from our selection of engineering plastics, as these are non-conductive and compatible with sensitive assemblies.
