T 6170 Reinforcement Plate (H-028) Dimensions

T 6170 Reinforcement Plate (H-028) Dimensions reference image

Reinforcement Plate (H-028) manufactured to T 6170 are dimensioned by the size table reproduced on this page. The standard fixes geometry and tolerances only; material and property class are assigned by ISO 898-1/898-2, and surface finish by separate finish standards.

T 6170 — Scope

T 6170 specifies the dimensions and tolerances of reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). Material, property class, surface finish and packaging are governed by separate documents in the same standards family (for example ISO 898-1 for the mechanical property classes of bolts and screws).

Tolerance & Product Grades

T 6170, alongside the related GB/T 6170 / ISO 4032 entries on this site, specifies product grades (typically A or B for fine work and C for general engineering) and tolerance classes for the controlling dimensions. Choose the grade against the precision your application requires.

Companion Standards

T 6170 controls only the geometry of reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). The mechanical strength is set by ISO 898-1 (bolts and screws) or ISO 898-2 (nuts); the surface finish is governed by separate finish standards (e.g. ISO 4042 for electroplating). For corrosion testing, the relevant document is ISO 9227 (neutral salt spray).

When to Specify T 6170

Choose T 6170 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065).

Frequently Asked Questions

Does T 6170 specify the mechanical strength?

No. T 6170 controls only the geometry of reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). The mechanical strength is set by ISO 898-1 (bolts / screws) or ISO 898-2 (nuts), and the finish is governed by separate standards.

Can I substitute T 6170 for the corresponding DIN standard on a drawing?

On modern drawings the ISO standard is the master reference; the older DIN equivalent is a cross-reference. For most dimensional purposes the parts are interchangeable, but check tolerance grades and the head height — these are the most common points of divergence.

When did T 6170 last revise its dimensional table?

ISO standards for reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065) are reviewed on roughly a five-year cycle. Always reference the latest published edition (or the edition cited contractually); the dimensional table on this page reflects the current commercially-supplied form.

What does T 6170 specify for Reinforcement Plate (H-028) — GB/T 6170 / ISO 4032 (Series 065)?

T 6170 specifies the dimensions and tolerances of reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). Material and property class are governed by separate standards in the same family.
