DIN 7996:2016 Round Head Phillips Wood Screw is characterized by a Phillips round head and wood screw thread and is intended for wood joints requiring faster power-tool tightening while retaining a rounded visible head.
The Phillips drive suits volume assembly, the round head forms a distinct but smooth bearing point, and the wood thread provides reliable pull-down force in fibrous materials. In assembly, the design helps reduce supporting operations, improve positioning consistency, and maintain good interchangeability in repeated production or field service.
Typical applications include wood furniture, crates, timber brackets, door and window accessories, and light decorative parts. The product can be configured with zinc plating, nickel plating, stainless steel, or colored coatings to suit indoor, outdoor, light-load, vibration-exposed, or export supply conditions.
