Tapping Screws

Why FF-S-200 Is a Genuinely Different Fastener Class
A machine screw under FF-S-210 assumes a matching thread already exists — either tapped into the base material beforehand, or provided by a separate nut. A tapping screw under FF-S-200 does something the machine screw can’t: it creates its own mating thread as it’s driven, either by physically cutting away material (thread-cutting types) or by displacing and reforming material around the screw without removing any (thread-forming types). Self-drilling variants go a step further, combining a drill-point tip with the tapping thread so the screw can create its own pilot hole and thread in one operation.
That self-threading capability is exactly why tapping screws exist as a distinct fastener class — they eliminate a separate tapping or drilling step in production, which matters enormously in sheet metal, plastic, and wood assembly work where drilling and tapping every hole separately would be prohibitively slow. Choosing between thread-cutting, thread-forming, and self-drilling comes down to the base material and whether swarf (removed material) or stripped-out holes from repeated use are a genuine concern.
Akbar Fasteners Pvt. Ltd. exports to over 50 countries, and our tapping screw range is manufactured across thread-cutting, thread-forming, and self-drilling types, verified by mechanical and dimensional testing under our ISO 9001:2015 quality system.
Where FF-S-200 Genuinely Applies
Eliminates a Separate Tapping Operation
Cuts or forms its own mating thread, saving a production step versus machine screw assembly.
Case-Hardened for Thread-Cutting Strength
Hardened surface with tougher core allows the thread to cut without the screw itself failing.
Unambiguous Federal Specification
Removes ambiguity in government purchase orders needing a defined tapping screw standard.
Verified Thread & Hardness Quality
Batch testing confirms genuine thread-cutting/forming performance, not just correct outer dimensions.
Type Options Explained
Type 1 / Type 23 / Type F
Physically removes material to cut a thread, generating swarf — best for harder or thicker base materials.
Type B / Type AB / Type U
Displaces material to form a thread without removing any — best for thinner sheet metal or plastic, reducing swarf risk.
Self-Drilling Tek Screws
Drill-point tip combined with the tapping thread, creating the pilot hole and thread in a single operation.
Pan / Hex Washer / Flat Head
Head profile selected for driving method, appearance, or bearing surface as the application requires.
FF-S-200 Tapping Screws vs FF-S-210 Machine Screws
Confirming which fastener class actually fits the assembly avoids specifying a screw that can’t do the job. This table is the quick reference we use with buyers before quoting.
| Aspect | FF-S-200 Tapping Screw | FF-S-210 Machine Screw |
|---|---|---|
| Mating Thread | Cuts/forms its own | Requires pre-tapped hole or nut |
| Base Material | Sheet metal, plastic, wood | Any tapped hole or nut |
| Production Step Saved | No separate tapping needed | Tapping/nut required beforehand |
| Typical Reusability | Lower (thread can strip) | Higher (thread is separate, robust) |
