Standard Equivalents

Equivalence is based on published standard-family information (Identical = interchangeable; Equivalent = dimensions/tolerances may differ, verify drawings before substitution).

System	Standard	Equivalence	Note
GB	GB/T 5783-2025	Identical	Chinese hex head bolt standard family
DIN	DIN 933	Equivalent	Common commercial equivalent; confirm thread/detail on order
ISO	ISO 4017	Equivalent	Common commercial equivalent; confirm thread/detail on order
ГОСТ	ГОСТ Р ИСО 4017-2013	Equivalent	RF national standard adopting ISO 4017 (full thread hex bolt)
EN	EN 15048	Equivalent	EN 15048 covers non-preloaded structural bolting ASSEMBLIES (bolt + nut + washer set), not single bolts. This site supplies the bolt component to GB/T 5783 (size basis ISO 4014 / ISO 4017); set requirements are confirmed per drawing.
GB	GB/T 5782-2025	Identical	Chinese partially threaded hex bolt standard family
ISO	ISO 4014	Equivalent	Common commercial equivalent; confirm thread length on order
DIN	DIN 931	Equivalent	Common commercial equivalent; confirm thread length on order
ГОСТ	ГОСТ Р ИСО 4014-2013	Equivalent	RF national standard adopting ISO 4014 (partially threaded hex bolt)
GB	GB/T 5789-1986	Identical	Chinese hex flange bolt standard family
ISO	ISO 4162	Related standard	ISO 4162 is the small series (smaller dc and s, e.g. M12 dc 24.7 / s 15); different dimensional system, not interchangeable
DIN	DIN 6921	Related standard	dc identical size by size; s and k differ from M12 up (M12 s 18 vs 16, M14 21 vs 18, M16 24 vs 21); not interchangeable

FAQ

MOQ and lead time?

Sourced per order or made to drawing. MOQ and lead time are confirmed at quote time by quantity, material and finish. Other sizes in this family are listed above; unlisted specs can be sourced to your drawing.

Can material or grade be substituted?

Current grade: Quenched & tempered, Rm≥800 MPa (Rp0.2=640), standard high-strength. Swapping grade/material changes strength and corrosion resistance (e.g. 8.8→10.9 raises strength, 304→316 raises chloride resistance), re-check design load and environment before substitution.

How do I choose the finish?

Electro zinc: indoor rust protection, cost-first. Other finishes (HDG, Dacromet, electro zinc) can be quoted on the same size.
