Fastening Devices

The following fastening devices are the chief means by which pieces of wood are fastened together: nails, screws, bolts, plates, dowels, glue, hinges, and locks.

Nail Products - may be classified according to the material of which they are made; as, steel, iron, copper, and brass. Iron nails may be galvanized to protect them from rust.

Small Screws - are fastening devices that may be classified by the material of which they are made; as, steel or brass. Steel screws may be either bright,—the common finish,—blued by heat or acid to hinder rusting, tinned, or bronzed.

Square Head Bolts and Other Bolts - Square head bolts with nuts are useful where great strength is desired. There are three chief varieties, Fig. 230.

Glue - is an inferior kind of gelatin, and is of two kinds,—animal glue and fish glue. The best glue is made from hides of oxen, which are soaked in lime water until fatty or partly decayed matter is eaten out and only the glue is left.

Stainless steel hinges, Fig. 233, are made in several forms. The most common are the butt-hinge or butt, the two leaves of which are rectangular, as in a door-hinge; the strap-hinge, the leaves of which are long and strap-shaped;

Hinging - In hinging, setting the hinges of a box cover, first see that the cover fits the box exactly all the way around.

Home Locks - The chief parts of home locks are: the bolt, its essential feature, the selvage, the plate which appears at the edge of the door or drawer, the box, which contains the mechanism including the tumbler, ward, spring, etc.

Inserting Key Locks - To insert a rim-lock, measure the distance from the selvage to the key-pin, locate this as the center of the keyhole, and bore the hole.
