obengs

Obengs are hand tools used to drive screws. A typical obeng consists of a handle attached to a shaft ending in a driving tip that matches the screw head. The plural form obengs is used in Indonesian and Malay contexts; in English, the tool is usually called a screwdriver.

Obengs come with a variety of tip designs to suit different screw heads. Common types include flat-head (slotted), Phillips, Pozidriv, Torx, hex (Allen), and square (Robertson). Specialty tips exist for security screws. Shafts are usually made of hardened steel, and tips are shaped and hardened for durability. Handles range from traditional wood to plastic and rubberized grips, with insulated versions designed for electrical work. Manual screwdrivers are complemented by powered tools such as electric drills, electric screwdrivers, and impact drivers.

Uses span carpentry, metalworking, electronics assembly, furniture making, and general maintenance. For electrical applications, insulated obengs with appropriate voltage ratings help prevent shocks, and workers should observe proper safety procedures.

Care and safety: choose the correct tip size and type to avoid cam-out and damage to the screw. Apply steady, controlled pressure and avoid using screwdrivers as prying tools. Inspect for wear, corrosion, or cracks, and replace damaged parts. Keep tips sharp and clean; store in a dry place.

Origin and note: the obeng has a long history in toolmaking, with designs evolving to accommodate a range of screw heads and industrial standards.
