Tapping screws are designed to join 2 pieces of sheet metal together.
Self Tapping screws were first used in the early 1950s, when they were used in sheet metal.
Our tapping screws are also known as sheet metal screws. These have a sharp Type “A” thread with a moderately sharp gimlet point. The threads are widely spaced. Sheet metal screws are used in thin gauge metal.
The material being fastened is light gauge steel and is often soft. The holes in the material are usually pre drilled or pre punched.

Ford Type A Sheet Metal 410 Bright Hardened Stainless Steel Tapping Screws
Tapping screws form their own threads as they advance, creating a secure mechanical connection without requiring pre-tapped holes. As the screw rotates, the point displaces material and the threads carve a matching profile into the substrate. This process produces a tight, vibration-resistant fit that is especially valuable in thin-gauge metals where traditional tapping would be impractical. The hardened 410 stainless construction enhances this effect by maintaining thread shape under load. Thicker metal often requires a pre-drilled hole.
Why Point Style Matters in Tapping Applications
Different tapping screw types are designed to address specific installation challenges. Type A screws are suited for thinner materials where a sharp point and wider thread spacing help establish a clean entry. Type B screws use a more controlled point and finer threads, making them ideal for slightly thicker metals or applications requiring a smoother driving action. Understanding these distinctions helps ensure the screw engages properly and maintains long-term stability.
Key Factors to Consider When Selecting a Tapping Screw
Choosing the right tapping screw depends on several practical considerations that influence performance and durability:
Material Thickness — Determines whether a Type A or Type B point is more appropriate.
Thread Engagement — Influences holding strength and resistance to loosening.
Head Style Requirements — Affects torque transfer, clearance, and final appearance.
Corrosion Protection — Guides decisions about coatings, finishes, and material selection.
When Hardened Stainless Steel Provides an Advantage
Bright-hardened 410 stainless steel offers a balance of strength and corrosion resistance that makes it well-suited for tapping applications. The hardening process allows the screw to cut threads efficiently while maintaining structural integrity during installation. At the same time, the stainless composition provides a clean, polished appearance and improved resistance to staining or surface degradation. This combination makes 410 tapping screws a dependable choice for both functional and aesthetic applications.
FAQs
What Is the Difference Between Type A and Type B Tapping Screws?
Type A screws have a sharp point and wider thread spacing for thinner materials, while Type B screws use a more controlled point and finer threads for slightly thicker metals. Type B screws have a blunt point as well.
Do Tapping Screws Require a Pilot Hole?
In many thin-gauge applications, tapping screws can form their own threads without a pilot hole, though harder materials may still benefit from one.
Why Choose 410 Stainless for Tapping Screws?
410 stainless provides the hardness needed for thread-forming while offering a stainless-steel appearance and improved corrosion resistance.
Can Tapping Screws Be Used with Coated or Painted Metal?
Yes, as long as the point style and thread design are matched to the material thickness to ensure clean penetration without damaging the surface.
These screws are sometimes called thread forming screws. As the screws are being installed, they form their own mating thread when joining 2 pieces of metal.
This allows for disassembly and reassembly.
If the material is too thick, then self drilling screws are needed. While our tapping screws were not made for wood due to the thread design, in some applications they can be used in wood. However, if they are, then a small pilot hole might be necessary due to the hardness of the wood. Do not overtighten. They can strip out because some grades of wood are hard.
They can also be used in plastic in some cases.
What is 410 Stainless?
410 is commonly used in mildly corrosive environments.
They are hardened by heat treatment
410 is the only grade of stainless steel that can be hardened by heat treatment.
This is ideal for tapping screws
410 stainless with an additional 1000 Hour salt spray Coating
If higher corrosion protection is needed, then we offer 1000 hour salt spray coating.
This coating provides additional protection from the elements.
Features of 410 Type A Sheet Metal Screws
Our 410 screws are usually used in many exterior applications.
They are used in mildly corrosive environments.
They are hardened by heat treatment. Our screws are bright hardened and passivated. They have a shiny stainless-steel appearance. This allows for easy identification in the field.
Our screws are slightly magnetic which allows them to attach to magnetic hex drivers. This is ideal for one hand installation which saves time.
This is ideal for hardened tapping screws.
Features of Type B Screws
Type “B” screws have a blunt point. They are used in extrusions and drilled holes. The screw forms its own thread.
Head Types
Indented Hex Washer Head Tapping Screws Type A for fast installation in high production applications. One Hand installation with a magnetic bit allows for fast installation.
Indented Hex Washer Head Tapping Screws Type A with EPDM Bonded Sealing Washer This provides moisture protection, noise reduction, and vibration control
Slotted Indented Hex Washer Slot provides additional versatility and accessibility in tight spaces.
Phillips Flat Countersunk head with a flush non-protruding surface.
Phillips Oval Countersunk head, slightly rounded top. For decorative uses
Phillips Pan Rounded Head, Common Head style
Phillips Truss Wide head, Low head height, the head has a larger bearing surface. This reduces crushing on thin metal and reduces sheet metal pulling over the head of the screw.
