Locks and locking systems are mechanical fastening devices designed to close and control access to doors, drawers, or containers. Common types of locks include cam locks, combination locks, deadbolts, padlocks, and key-operated locks

Masters and setting gages provide dimensional standards for calibrating other gages

Shaft-hub locking devices frictionally clamp gears, pulleys, flywheels, and other components to a shaft without the need for threads or keys

Floor locks are mechanical components with an adjustable-height pad. They prevent portable equipment from rolling

Precision locknuts are used to secure bearings, gears, and other power transmission products to shafts and spindles.

Master alloys and alloying additives are alloy element concentrates, grain refiners, hardeners, deoxidants and other agents added into a melt or metal powder blend to produce a particular alloy, modify a melt or alter processing characteristics

Latches are mechanical components that hold a door, drawer, or cabinet closed. Typically, latches do not lock; however, some latches provide locking features

Door and window hardware is used to lock, handle, or hinge doors and windows

Interlocks and tag out devices "lock out" valves, electrical switches or other components. These devices are used typically during service or maintenance of machinery or process equipment

Thread lockers and retainers render threaded fasteners immovable. They are used mainly with devices that are subject to transverse and axial loads that may lead to vibrational loosening.

Calibration standards and reference sources include any source that can provide a reference for the calibration of an instrument or comparison of a material or component.

Office, graphic art and library products and supplies are used in offices, graphic arts studios, and libraries.

Washers are disks of metal or non-metallic material placed beneath a nut, an axle bearing, or a joint, to relieve friction, prevent leakage, isolate, prevent loosening, or distribute pressure.

Quick couplers are used in hydraulic or pneumatic systems to quickly connect lines without losing fluid or fluid pressure.

Industrial storage products include cabinets, containers, coolers, carousels, garages, hoppers, lockers, mezzanines, racks, shelves, shelters, storage tanks, and walk-in enclosures.
