Products Description

Stainless Steel Full Thread, also known as Full Threaded Bolt and Through Threaded Screw, is a continuous full-length threaded stud manufactured in strict compliance with DIN976 international standard. Entirely threaded along the whole shank without smooth unthreaded section, it serves as universal lengthening, connecting, suspending and positioning fastener. Made from premium 304 / 316 stainless steel with A2-70 & A4-70 high strength grades, it delivers outstanding corrosion resistance, tensile stability and dimensional precision, ideal for outdoor, coastal, humid, slightly acid/alkali harsh environments across construction, chemical, marine, food machinery and industrial assembly sectors.

Material & Grade Performance Breakdown

1. Material Corrosion Resistance Advantages

304 Stainless Steel (A2-70): Contains ~18% chromium + 8% nickel alloy composition. Offers reliable anti-rust performance under atmospheric exposure, fresh water, indoor humidity and weak acid/alkali working conditions. Cost-effective general-purpose grade for most conventional industrial, civil construction and indoor-outdoor standard fastening scenarios.
316 Stainless Steel (A4-70): Added molybdenum element, far superior salt spray and chemical corrosion resistance. Resists seawater erosion, coastal salt fog, strong humidity and mild chemical medium corrosion, the top choice for marine engineering, coastal construction, food processing equipment and chemical workshop use.

2. High Strength Grade Stability

A2-70 and A4-70 undergo cold working hardening treatment, achieving high tensile strength while retaining proper toughness. No permanent elongation or thread deformation under rated tension load, ensuring long-term stable clamping force for suspended loads and structural splicing connections.
