The Tenn-Tex #8-32 x 3/8" flat head machine screw is a short-reach fastener built for attaching cabinet knobs, pulls, and decorative hardware to doors and drawer fronts. The 3/8" length keeps the screw well clear of the back face on standard door and drawer-front stock, and the flat head countersinks flush for a finished appearance at the hardware base.
Cabinet hardware typically ships with machine screws sized for a range of door and drawer-front thicknesses. When the stock is on the thinner side — veneered doors, inset frames, or drawer fronts routed for recessed pulls — a shorter screw prevents the tip from pushing through the back face and creating a visible bump or snag. The 3/8" length is also the right choice when the hardware itself is shallower and leaves less thread engagement depth to work with. For standard 3/4" stock with deeper hardware bodies, confirm thread engagement before substituting a shorter screw.
These screws are zinc-plated steel with a fine #8-32 thread and a blunt point, as machine screws thread into a pre-tapped hole or a nut rather than cutting their own path. The flat head is a standard 82-degree countersunk profile that seats in a matching countersink. Zinc plating is appropriate for dry indoor environments — kitchen and bath cabinetry, furniture, and built-ins — where the hardware is not exposed to moisture or outdoor conditions.
Cabinet installers and shop assemblers who stock a range of machine screw lengths keep these on hand for thin-door and shallow-hardware situations. Designers specifying custom or semi-custom hardware often call out screw length separately from the hardware order to match exact stock thickness. Homeowners replacing a pull or knob on a veneered or routed door will find the 3/8" length handles the job cleanly where a longer screw would not.
If your hardware uses the standard North American thread — which is #8-32 for the vast majority of cabinet knobs and pulls — yes. Check the hardware spec sheet or the screws that came with it to confirm the thread standard before ordering.
Measure from the face of the door to the back surface, then subtract the depth of the hardware body. The screw should thread fully into the hardware without the tip reaching the back face. On thinner veneered doors and shallow pulls, 3/8" is often the correct call.
Yes. Machine screws have a blunt point and threaded shanks that require a pre-drilled clearance hole through the door or drawer front. The hardware itself is typically pre-tapped to accept the screw from the other side.
Zinc plating is suited to dry indoor applications. For exterior hardware or high-humidity environments, a stainless or more corrosion-resistant fastener is the better choice.
With 200 screws per bag, there is enough here to finish a full cabinet run or keep as shop stock for the next hardware order that comes in short on fasteners.
