GOST 5663-79 PDF

Full title and description

GOST 5663-79 — Cold heading carbon steel wire. Specifications (Russian: ГОСТ 5663-79 — Проволока стальная углеродистая для холодной высадки. Технические условия). The standard defines requirements for manufacture, surface condition, dimensional tolerances, mechanical properties and packing of carbon steel wire intended for cold heading (cold upsetting) processes.

Abstract

GOST 5663-79 specifies technical conditions for carbon steel wire produced for cold heading (cold upsetting) operations used in the manufacture of fasteners and other cold-formed parts. It includes permitted steel grades, diameter ranges and tolerances, surface quality limits (allowed dents, scratches, absence of cracks, scale and delamination), mechanical classes, testing and marking/packaging rules.

Scope

The standard applies to cold-heading carbon steel wire produced for subsequent cold upsetting/forming into fasteners and other stamped/cold-formed parts. It covers wire manufacture from defined steel grades, dimensional and surface quality requirements, mechanical property classes, testing methods, marking and packaging suitable for industrial supply and further cold forming operations. Intended for producers, purchasers and quality laboratories dealing with cold-heading wire.

Key topics and requirements

• Permitted steel grades (examples: series of low-carbon and constructional carbon steels per relevant GOST references).
• Diameter ranges and dimensional tolerances for drawn wire used in cold heading.
• Surface quality rules — prohibitions on cracks, delamination, heavy scale; allowable small dents and scratches within defined depth limits relative to tolerance.
• Mechanical property classes and testing requirements (tensile, elongation where applicable) appropriate for cold heading performance.
• Packing, marking and coil/motka (coil) mass/labeling requirements for traceability and handling in production.

Typical use and users

Used by wire manufacturers, metalworks, fastener producers, quality/control laboratories, procurement specialists and engineers in automotive, construction, hardware and general engineering industries where cold-formed fasteners (bolts, screws, rivets, nails) and similar parts are produced by cold heading or cold stamping. Distributors and wholesalers of drawn wire also rely on the standard for specification and acceptance.

Related standards

Related Russian and interstate standards cover other wire types and processing (e.g., standards for spring wire, cold-drawn wire, wire rod and complementary material/heat-treatment specifications). GOST listings and product-class standards (multiple GOSTs in the V7x / wire groups) are commonly referenced alongside GOST 5663-79 for complete material and product specification.
