Stainless Steel Cheese Head Slotted Screw
Key Specifications
Choosing the Right Stainless Steel Cheese Head Slotted Screw
1) What is a cheese head slotted screw & when should you use it?
A cheese head slotted screw is a cylindrical, tall head screw with a straight (slotted) drive. Compared to pan/round heads it has:
A tall, straight-sided cylindrical head
A flat top with a single slot
Smaller head diameter than pan, but greater head height
Use a cheese head slotted screw when you need:
A high head that is easy to grip and turn with a screwdriver or by hand (for assembly/adjustment)
A compact head diameter that doesn’t interfere with surrounding parts
A more “classic” or traditional look for old machinery, restoration work, panels, instruments, etc.
Typical applications:
Electrical and control panels
Instruments, meters, machine covers
Older machines / restoration / retro-fit work
Jigs, fixtures and clamps needing a tall head for access
2) Head style – why cheese head instead of pan / CSK / hex?
Cheese head (your product):
Tall cylindrical head, small-ish diameter
Easy to access in recessed areas where a wider head would clash
Suitable where head height is available, but head diameter must be limited
Pan / round head:
Lower, dome/pan-shaped with wider head diameter
Better for spreading load on thin sheet without washer
More modern appearance, but larger diameter may clash with nearby walls/slots
Countersunk (CSK):
Conical head, sits flush with the surface
Best where the surface must be flat, but requires a countersunk hole
Hex / Allen cap:
For higher strength and torque with wrench/Allen key drive
Used where strong tightening is more important than traditional slotted appearance
Choose cheese head slotted when:
You want a tall, visible head for screwdriver access
There is limited space around the head but enough space above
The design calls for traditional slotted screws (electrical/instrumentation, retro/industrial look)
3) Drive type – slotted head selection
Slotted drive:
Single straight slot across the top
Can be driven with a normal flat screwdriver
Common in panels, terminals, electrical & older industrial equipment
Pros:
Very universal tool availability
Classic appearance
Cons:
More prone to cam-out (screwdriver slipping) than Phillips/Pozi/Allen
Less suitable for very high torque or power-driver assembly
For your catalogue, cheese head slotted screws are ideal where:
Assemblies are hand-assembled or serviced manually
Torque is moderate, not extreme
A traditional, simple head is desired
Mechanical Properties (Guide)
Mechanical Properties (Guide) – Cheese Head Slotted Screw. The mechanical strength is governed by the material grade and thread diameter, not by the head style alone. The cheese head and slotted drive mainly limit the practical tightening torque.
Stainless Steel Cheese Head Screws (A2 / A4)
Typical minimum properties:
A2-70 / A4-70
Tensile strength ≈ 700 MPa
Proof strength ≈ 450 MPa
A4-80 (where available)
Tensile strength ≈ 800 MPa
Proof strength ≈ 600 MPa
Behaviour:
Good combination of strength + corrosion resistance.
Ideal for stainless panels, covers, equipment housings, clamps and fixtures.
Stainless threads are more prone to galling if assembled into stainless nuts/inserts – use:
Anti-seize / thread lubricant,
Metric coarse threads,
Controlled tightening.

Frequently Asked Questions
A cheese head slotted screw is a machine screw with a tall, cylindrical head and a single straight slot on top.
Compared to a pan head, it has:
More head height (taller head)
A smaller head diameter
A flat top with a straight slot for a flat screwdriver
It’s widely used in electrical panels, instruments, covers and machine assemblies.
Use a cheese head slotted screw when:
You need a tall head that’s easy to reach with a screwdriver
There is limited space around the head (small head diameter helps)
The design prefers a traditional slotted look (electrical / instrumentation / retro machinery)
Use pan head when you want a wider bearing area on thin sheet.
Use CSK (countersunk) when the screw has to sit flush with the surface.
Typical uses:
Electrical and control panels
Terminals, instruments, meters, measuring devices
Machine covers and access doors
Jigs, fixtures, clamps and toolroom assemblies
Restoration / retro / classic equipment that originally used slotted screws
They’re ideal where screws are visible and frequently accessed with a screwdriver.
Not really. Slotted drives are:
More prone to cam-out (driver slipping)
Limited in torque capacity compared to Philips/Pozi/Allen/hex drives
Cheese head slotted screws are best for light–medium duty clamping and panel/cover fastenings.
For high-torque or structural joints, use hex bolts or Allen cap screws.
SS 304 (A2) screws can be slightly magnetic due to cold working during manufacturing.
SS 316 (A4) is usually less magnetic, but light magnetism is still possible.
If a customer requires strictly non-magnetic screws, that must be clearly specified.
