Anatomy of a Screw — Self-Threading, No Nut Required
A screw works on a fundamentally different principle from every bolt on our site. A bolt is designed to be used with a nut, or into a hole that has already been tapped with a matching thread, and is typically torqued using a wrench acting on the head. A screw instead creates or engages its own thread as it is driven — cutting or forming that thread directly into wood, sheet metal, plastic, drywall, or a plain pre-drilled pilot hole, with no nut required at all, and typically turned by a screwdriver bit.
Because a screw’s holding strength comes entirely from the thread it forms in the surrounding material, pilot hole size, material thickness, and thread pitch all matter enormously to correct screw performance in a way that doesn’t apply the same way to a bolt threading into an existing tapped hole or nut. Getting the screw type matched correctly to the base material — wood, thin sheet metal, or drywall — is the single most important specification decision for this product category.
This page covers our complete screw range across all base materials and coatings — for the full technical detail on stainless steel screws specifically, including passivation and drive-type selection, see our dedicated Stainless Steel Screws page.
Why Screws — Fast, Direct Fastening Without a Nut
No Access Needed to the Opposite Side
Because a screw’s holding thread forms in the material itself, it can be driven from one side alone with no need for tool access, a nut, or a clearance hole on the far side of the joint.
Fast, Single-Operation Installation
A power driver can seat a screw fully in one continuous operation, particularly with self-drilling types that bore their own pilot hole — significantly faster than a bolted connection requiring separate drilling, tapping, and torquing steps.
Available Across Every Common Base Material
Wood, sheet metal, plastic, drywall, and pre-tapped machine applications each have a purpose-built screw type — the correct fastener exists for essentially any thin or self-threadable base material.
Full Range of Material and Coating Options
From economical zinc-plated carbon steel through fully passivated stainless steel, screw material selection follows the same corrosion, strength, and cost trade-offs as our bolt and nut range.
Which Material Do I Actually Need?
Screw base material and finish follow the same selection logic as our bolt and nut range — find your actual requirement below.

For applications genuinely needing a nut-and-bolt connection rather than a self-threading screw.
View Hex Bolts →Screw Categories We Manufacture
Each category threads into a different base material by a genuinely different mechanism.
Wood Screws
Coarse, deep thread cutting directly into timber with only a plain pilot hole needed.
Self-Tapping Screws
Sharp thread cutting its own mating thread into thin sheet metal or plastic.
Machine Screws
Uniform machine thread for use with a nut or pre-tapped hole — bridges screw and bolt logic.
Self-Drilling (Tek)
Integral drill tip bores its own pilot hole through sheet metal in a single operation.
Drywall Screws
Fine or coarse thread with a bugle-shaped head that seats without tearing paper facing.
Screw Head Types We Manufacture
Head shape determines bearing area, flush-mount capability, and finished appearance.
Pan Head
Rounded top with a flat bearing face — the most common general-purpose head profile.
Flat / Countersunk
Conical underside sits flush with the surface for a snag-free, finished appearance.
Round Head
A domed, decorative profile providing a larger bearing surface than a flat head.
Hex Washer Head
Integral washer and hex drive combine wrench-driving with a wide bearing area.
