    • Our take on the #12-24X1-1/4" Slotted Round Head Machine Screws, Steel Zinc, 500 Pack

    These are #12-24 coarse-thread machine screws with a 1-1/4" length under the head, a slotted round head and a zinc clear finish over steel. They are fully threaded, so they clamp along their whole length and suit through-bolts and tapped holes where a flat-blade driver is fine. The round head sits above the surface and has no countersink, so they are not for flush mounting. The 500-piece pack suits shops and repeat assembly work; the slotted drive is the main trade-off against Phillips or hex rivals, which take more torque without slipping.

    Questions and answers

    What does 1-1/4" length under head mean?
    It is the length from the underside of the head to the tip of the screw, not counting the head itself. Account for the head height when checking whether the screw reaches through your parts.
    Are these fully threaded?
    Yes. The #12-24 coarse thread runs the full length under the head, so they clamp along the whole shank.
    What material and finish are they?
    Steel with a zinc clear finish. That gives light corrosion protection for indoor and sheltered use, not for constant moisture or marine settings.
    Will a slotted head work with a power driver?
    It can, but a flat-blade bit slips more easily than a Phillips or hex bit. Use a driver with a clutch and keep the blade matched to the slot width.
    What can these screw into?
    They are machine screws, so they thread into tapped metal holes or a matching nut, not into wood directly. The coarse #12-24 thread suits softer metals and castings.
    Is a 500-piece pack practical for home use?
    Only if you use this size often. For a one-off repair, a smaller quantity of the same screw is easier to store and less wasteful.
    Where is the #12-24X1-1/4" Slotted Round Head Machine Screws, Steel Zinc, 500 Pack cheapest?
    At Southeastern Supply, for $15.45, as of our latest check.
