Product Description
5/16"-18 x 2 1/2" Type F Thread Cutting Screws / Phillips / Flat Head / 18-8 Stainless Steel / Passivated / Made in USA
5/16"-18 x 2 1/2" thread-cutting screw in 18-8 Stainless Steel, passivated finish. For cutting a clean mating thread in brittle or hard material.
- FLAT HEAD — an 82° countersunk head that sits flush with the surface
- PHILLIPS DRIVE — the familiar cross recess; it is designed to cam out under load, so ease off the clutch at depth
- PASSIVATED — an acid treatment that strips free iron from the stainless surface so it cannot bleed rust down the workpiece
- FULL THREAD — threaded to the head, so it grips over the whole length and suits thin or variable stack-ups
- 18-8 STAINLESS — the 300-series austenitic workhorse — non-magnetic, excellent general corrosion resistance, and it will not rust-stain the surface around it
🇺🇸 Made in USAStainless
