Mechanical Connections

Hardware includes square, star, flat-head, and Phillips tip drivers and stainless steel, brass, or wall – board screws (Figure 8.44). Hardware also includes bolts, nuts, washers, pulls, full extension glides, casters, special cabinet hinges, or plated continu­ous hinges. Modez clips are useful in mounting panels and heavy objects to a vertical surface. Similar to the French cleat, which relies on gravity and two angled elements to secure the attach­ment, the modez clip is a two-part metal device that enables one element to fit into the other; then the two elements lock together via a keyhole with a simple sliding action.


■ Wood screws are made of brass, steel, or bronze. Steel wood screws are referred to as bright, and may be blued, lacquered, galvanized, chrome plated, or anodized.

■ Drywall screws are specialized screws that have a bugle head designed to attach wallboard to wood studs; however, they are a versatile construction fastener for furniture work as well as for most mechanical attachments. The length of the screw’s shank is the main determinant of holding strength in a wood connection, not the thickness of the shank.

■ Machine screws are available up to % inch in diameter. These fasteners are often used with nuts to secure connections. They can be considered a hybrid between a screw and a bolt.

■ Square drive screws and drivers are preferred by many craftspeople because they drive well, the heads won’t strip out, and the screws have small, relatively attrac­tive heads; the last is important, when considering them as an "expressed joint" detail.

Hardware, glides, latches, and casters need to perform well. The best possible quality ought to drive the selection.


■ Fender washers are similar to plain washers but have a large outside diameter and are used to distribute forces that are applied when tightening.

■ Finishing washers are contoured. They are especially engineered for oval-head screws and have a "finished" look. The help prevent the head of the screw from pulling through the material.

■ Lock washers (split lock washers) have a cut ring and are bent in a helical shape, causing the washer to exert a spring force between the fastener’s head and the material’s substrate.

■ Plain washers (flat washers) are a flat annulus or ring-shaped device, used to pro­tect the joined component and to spread the load of a screwed connection.

■ Tooth-lock washers are integrally and/or externally serrated. Bent teeth bite into the bearing surface upon tightening, which prevents the nut from turning and the fastening from loosening.

Drawer Glides

■ Bottom edge-mounted: These glides are mounted on the drawer side bottoms and to the cabinet interior. They are relatively easy to install but do not offer the full extension of side-mounted glides.

■ Central-mounted: These glides are mounted beneath the drawer center and are intended for lightweight applications.

■ Side-mounted: These glides are the most versatile in terms of extension, durability, and weight capacity. Side-mounted glides are mechanically secured to the side of the drawer and the cabinet interior. They typically require a Уг-inch depth for each side. Medium-duty (100 pounds) and heavy-duty (100-500) pound slides are available.
