A4 Stainless Steel Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100)

Specifying Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100) in A4 Stainless Steel pairs the dimensional form of Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100) (GB/T 120.1 / ISO 8735) with the engineering properties of A4 Stainless Steel. This page explains when to choose the grade, how it behaves in service, and which grades to compare it against.

Why Choose A4 Stainless Steel for Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100)

Specified for marine, coastal and chemical applications. For internally threaded dowel pin — gb/t 120.1 / iso 8735 (series 100), this matters when superior, including marine and chloride environments is the primary requirement.

Mechanical & Physical Properties

Galvanic & Galling Considerations

Two important notes for stainless internally threaded dowel pin — gb/t 120.1 / iso 8735 (series 100): (1) stainless can gall on stainless threads under load — use a thread lubricant or anti-galling compound, especially for M6 and below; (2) when joined to aluminum or galvanized steel, stainless can drive galvanic corrosion of the less-noble metal in wet service — isolate with a coating or sleeve where appropriate.

Comparable Grades

For Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100), the alternative stainless grade is A2 (304). A2 (304) suits general indoor and outdoor service; A4 (316) adds molybdenum for marine and chloride environments. Where higher strength matters more than corrosion, switch to plated alloy-steel class 8.8 or 10.9.
