Buy & Import Double Sided Screw Bolt from Shanghai T & Y Hardware Industry Co., Ltd. - Wholesale Supply

Double sided screw bolts from Shanghai T & Y Hardware Industry Co., Ltd. are threaded fasteners with male threads on both ends and a central unthreaded shank, designed for through-bolt applications requiring clamping between two components. Available in sizes from M4 to M42 and 3/8" to 7/8", they comply with DIN, ANSI, JIS, and IFI standards. Thread types include metric, UNC, and UNF, with surface finishes such as plain, zinc plated, hot-dip galvanized, DAC, and Geomet coatings applied as specified.

These bolts are manufactured from carbon steel, alloy steel, or stainless steel, with material grade selection dependent on application requirements. Carbon steel variants typically meet ASTM A307 Grade A or B, while stainless steel options follow AISI 304 or 316. The central shank is unthreaded to allow for precise torque control during assembly and to prevent thread damage in rotating applications. Surface treatments are applied to enhance corrosion resistance without altering dimensional tolerances.

These fasteners are commonly used in heavy machinery, structural steel connections, and industrial equipment where double-end anchoring is required. Buyers include manufacturers of automotive components, construction equipment, and pipeline systems. Packaging is offered in small boxes, poly bags, or cartons on pallets. Delivery typically takes 30 days, depending on order volume, with payment terms accepted via T/T, L/C, or Western Union.

Frequently Asked Questions About Double Sided Screw Bolt from Shanghai T & Y Hardware Industry Co., Ltd.
Carbon steel bolts sized M8 to M20 typically meet ASTM A307 Grade B with a minimum tensile strength of 600 MPa. For larger sizes, alloy steel grades such as ASTM A449 or ISO 898-1 Class 8.8 are used, achieving 800 MPa minimum. Buyers should specify the required strength class when ordering.

Sourcing Double Sided Screw Bolt from Shanghai T & Y Hardware Industry Co., Ltd. - China Import Guide

Before placing an order, verify the material grade, surface finish, and compliance standard with the supplier’s written documentation. Confirm that the bolt dimensions match your assembly requirements, particularly thread length and shank diameter. Request a sample for fit and function testing, especially if replacing existing fasteners in critical equipment.

Lead time is stated as 30 days but may vary with order quantity. Confirm Incoterms - whether FOB Shanghai or CIF destination - and ensure payment terms are clearly defined. TT and L/C are accepted; Western Union is not recommended for large transactions due to lack of buyer protection. Clarify whether packaging includes labeling per buyer specifications.

Perform visual inspection for coating uniformity and thread damage upon receipt. Use a thread gauge to verify pitch and diameter compliance. Retain a sample batch for third-party lab testing if required for certification. Ensure the supplier provides an MTR or certificate of conformity with each shipment, especially for alloy and stainless steel grades.
