Every axis this catalogue files a screw under, with the plain-English meaning of each value — the same definitions the filter shows.

Size#8A gauge is a diameter, not a length — measured across the outside of the threads. #8 is 0.164 in (5/32) crest to crest. Wood screw diameter chart
Length2"Lengths are nominal, as they are throughout the trade. A round washer head is measured from the bearing surface under the head, not the top of the head, because it stands proud of the work. How lengths are measured
DriveQuadrexA combined square and cross recess — takes either bit.
HeadRound WasherA dome sitting on an integral washer flange.
ThreadDeepA tall thread on a narrow core. Bites into loose material like particleboard and end grain.
PointSharpA plain gimlet point. Starts on its own in soft material with no pilot hole.

Cabinet & Furniture Screws  ·  Shipped from Jasper, Indiana

Cabinet Screws stocks one thing and stocks it properly: wood screws for cabinet and furniture work. Size, length, drive, head, thread, point, finish — choose each one, and the part is stocked in a 100 box, a 1,000 box and a box sized for the run. Expert, American phone support on (812) 639-0120 when you would rather just ask someone.

The Cabinet Screws Difference

A wood screw is seven decisions. We stock every combination of them — so the screw you specified is the screw you can actually buy.

Under 1 Inch

Face frames, hinge plates, drawer slides and hardware — where the screw must not break through the far side.

Shop the range →

1 to 1 7/8 Inch

The everyday range. Carcass joints, cleats, drawer boxes and most cabinet assembly.

Shop the range →

2 to 2 3/4 Inch

Thicker stock and joints that carry load, where you want real thread biting into the second piece.

Shop the range →

3 to 3 1/2 Inch

Hanging cabinets, blocking and framing — the long end of what we stock.

Finishes

The coating decides where it can live.

The same steel underneath. Finish is the last decision, and the one that settles whether a screw belongs in a painted face frame or the damp base of a sink cabinet.

Black Phosphate

Interior, takes paint

Zinc

General purpose

Dry Lube / Plain

Lower drive torque

Stat Bronze

Dark, decorative

Also stocked in nickel, black oxide, black and Ultraguard. Some parts are listed without a finish — the product page says which.

The unit of sale

Every part, three ways.

The unit of sale here is the box, not the screw. Every part in the catalogue comes as a 100 box, a 1,000 box, and a box sized for a production run — the same part number every time. Buy 100, prove the joint on the real material, then come back for the quantity the job actually needs.

It starts with the thread

How hard it bites.

Deep thread cuts further into soft cores — particleboard, MDF, the edge of a plywood panel — where a shallow thread strips out. Coarse thread takes fewer, wider turns and drives faster in solid stock. Then the point decides whether you drill first: a Type 17 clears its own chip, while a sharp point wants a pilot hole in hardwood.

Designed to hold

What the screw is actually doing.

The head seats here

Flush in a countersink, or proud of the face. That is the head you pick.

Only this part grips

The thread in the second piece is the joint. Length is how much you get.

The point starts the hole

How do I work out the length I need?
Measure the piece you are fastening through, then leave enough screw to hold in the second piece — as a working rule, at least half the length should land there. Every product page lists the length, and the collection pages are grouped by length range, so you can start from the size of the joint rather than from a part number.
Will my driver fit a Quadrex recess?
Yes. Quadrex is a combination recess: it takes a Phillips bit or a square (Robertson) bit, and it holds a square bit noticeably better under torque. If your crew is already set up for Phillips, a Quadrex screw drives with the bits you have — you simply get the option of a square bit where you want more grip.
Do I have to buy a bulk box?
No. Every part comes as a 100 box as well, and the part number does not change between box sizes. Buy 100, prove the joint on the real material, then order the quantity the run needs.
Which finish should I specify?
Black phosphate is an interior coating that takes paint well and is what most cabinet work uses. Zinc is the general-purpose plated finish. Dry lube reduces drive torque, which matters on long screws and in dense stock. If the joint will see moisture or any outdoor exposure, call us on (812) 639-0120 before you specify — we would rather talk it through than have you guess.
