Screw Comparison Guide

Use this Screw Comparison Chart to help choose the right screw that best fits your application. Compare Screw Heads, Screw Threads and size for either Interior or Exterior applications. Lube Finished Screws Application: Great for most standard interior applications. Choose from either Square Drive or Square-X Screws. Lube finish reduces friction for easier installation. Head: Flat Head Thread: Deep Thread Size: #6, #8, #10 Trim Head Square Drive Application: Trim Molding. Finish nail look with the power of a screw. Head: Small 3/16" Trim Head Thread: Deep Thread Size: #6 Slide Mounting Screws Application: Ball bearing slides and catches, drawer slides, shelf supports. Low profile head won't interfere with guide operation. Strong holding power. Head: Truss Head Thread: Deep Thread Size: #6 Truss Head Break Away Application: Knobs and Pulls. Breaks away in 1/4'. Great where length of screw is not pre-determined. Head: Truss Head Thread: Machine Thread Size: #8 Drawer Pull Screws Application: Used for drawer knobs and pulls. Holds knobs and pulls secure.

Screw Heads

Here are top and side views of many of the screw-head styles you'll encounter. Top row, left to right: flat head, flat head with a separate finishing washer, washer head, and truss head. Bottom row, left to right: round head, oval head, pan head, fillister, and trim head. You can buy screws with a variety of head styles to meet specific project needs and can often select the fastener with your favorite drive system. Here's a quick rundown on the uses for the most popular types.

Flat-Head Screws:

Probably the most common style and are used in a wide variety of applications, from general construction to fastening tiny hinges. The head is typically flat with the surface of the wood, or it can be driven into the bottom of a counterbore and concealed with a plug. It's also the right choice to use with finishing washers.

Trim-Head Screws:

Look like finishing nails and can be used wherever you need the holding power of a screw but also require an unobtrusive look.

Round-Head Screw:

Gives you the broadened holding strength of a washer under a screw head but without the inconvenience of purchasing and handling a separate piece of hardware. By spreading the pressure, the washer-head screw avoids concentrated stresses that could crack plastics or damage thin wood products.

Oval-Head Screws:

Mount with their smooth top just above the wood's surface. This gives a decorative look and also prevents the snags produced by flat-head screws that aren't fully countersunk. The oval head finds extensive use holding trim to boats.

Pan-Head Screws:

Have a flat surface under the head that improves holding power when you mount hardware such as drawer slides. Using a screw diameter smaller than the mounting hole in the hardware gives you some adjustability.

Truss-head screws:

Feature an even larger washer surface for improved holding power. Truss heads are excellent for attaching false drawer fronts - large head hides an oversized hole that permits adjustment. Truss heads also provide excellent holding power when driven through the thin plywood backs of wall-mounted cabinets.

Excerpted from Taunton's Complete Illustrated Guide to Hardware Copyright 2003 The rolled-thread screw and cut-thread pattern are two dominant fastener designs used by woodworkers. Deep-Thread Pattern: (Also called Rolled thread). This style is manufactured by slimming the screw's shank (in comparison to the cut-thread patter wood screw). Excellent all-purpose design for solid wood, plywood, medium-density fiberboard (MDF) and other manufactured panels. Wood-Screw Thread: The thread design is similar to the deep-thread pattern but formed on a thicker shank. This design is often used on relatively soft materials such as brass or silicon bronze screws. Use this pattern instead of the deep thread when your project requires brass or bronze screws. Double-Lead: This pattern uses two threads around the shank for increased driving speed, is commonly used on drywall screws, and sometimes has a high/low design. Pullout resistance is not as good as the deep-thread design, but you'll gain faster assembly times, especially when you're using long screws. Cut Thread: (Also called tapered wood thread). This is the traditional wood-screw pattern, which mimics the old-fashioned process of cutting the threads into a metal rod. The unthreaded portion of the shank is the same diameter as the major diameter of the threaded portion, and the root diameter tapers to the tip. The thread depth is consistent along the length of the screw, even in the tapered portion, accentuating the pointed appearance. Good holding power in solid wood. Tapping Thread: Although this is some-times called a "wood-tapping" screw, it is basically a sheet-metal design. Typically the threads extend from tip to head. Sheet-metal screws are generally manufactured to a higher standard than ordinary wood screws. Be sure to drill an adequate body hole in the first board to prevent a jaced joint.
