Product Description
1/4"-20 x 5/8" Type F Thread Cutting Screws / Slotted / Hex Washer Head / Low Carbon Steel / Zinc
1/4"-20 x 5/8" thread-cutting screw in Low Carbon Steel, zinc finish. For cutting a clean mating thread in brittle or hard material.
- HEX HEAD — driven with a socket or wrench, so you can put real torque through it without a bit camming out
- SLOTTED DRIVE — a straight slot for hand driving, restoration and period work
- ZINC PLATED — an electroplated barrier for interior and sheltered work; it will not survive sustained weather or contact with treated lumber
- FULL THREAD — threaded to the head, so it grips over the whole length and suits thin or variable stack-ups
- CARBON STEEL — strong and inexpensive, but it depends entirely on its plating for corrosion protection
RoHS Compliant
