Import 304 Flat Head Phillips Screw — Buy in wholesale FOB from Supplier in China

The 304 Flat Head Phillips Screw from Shenzhen Xintegu Hardware Co., Ltd is an austenitic stainless steel fastener combining 18% chromium and 8% nickel in its alloy composition, delivering the corrosion resistance characteristic of 304-grade material with a countersunk head geometry suited to flush-surface installations. The flat (countersunk) head profile seats below or level with the workpiece surface when driven, while the Phillips cross-recess drive accepts a cross-point driver for controlled torque transfer and reduced cam-out during assembly. This screw is manufactured from cold-formed wire stock with rolled threads, a process that preserves grain flow and enhances tensile properties compared with cut-thread alternatives.

The 304 stainless steel designation conforms to ASTM A193 and Chinese GB/T standards for austenitic chromium-nickel steels, with typical hardness of 70-90 HRB in the annealed condition and tensile strength around 515 MPa. The flat head angle is standardised at 82 degrees for imperial sizes and 90 degrees for metric series, though buyers should confirm which convention applies to a given batch. Passivation is the typical surface treatment, restoring the chromium oxide layer after machining and forming; additional electropolishing can be requested for medical or clean-room applications. The Phillips drive specification follows ANSI/ASME B18.6.3 for machine screws or equivalent, with recess proportions matched to driver size #1, #2, or #3 depending on nominal screw diameter.

Primary buyers include furniture manufacturers requiring invisible fixings on visible surfaces, electrical enclosure builders needing flush interiors to avoid contact with live components, and marine equipment fabricators exploiting the 304 alloy's resistance to salt spray in above-waterline applications. Automotive trim suppliers also specify this head style for interior panels where protruding fasteners would snag fabric or compromise aesthetics. For importers, the critical verification is thread pitch series (coarse UNC, fine UNF, or metric ISO) and drive recess depth tolerance, as these determine interchangeability with existing tooling and tapped holes.

Shenzhen Xintegu Hardware Co., Ltd maintains a registered address at 201, No. 13, Fengming Road, Fengdeling, Fenggang Town, Dongguan, Guangdong, China, 523693, placing its operations within the Pearl River Delta manufacturing corridor rather than central Shenzhen itself. The company holds a harbor trust tier on its marketplace profile, and its response rate is recorded at 0.00% with zero average response hours, indicating no inquiry engagement data is currently available through the platform. The supplier's profile does not disclose factory size, annual turnover, employee count, or specific quality certifications, so buyers should request ISO 9001 or IATF 16949 documentation directly if required for their supply chain audits.

The listing positions Shenzhen Xintegu as a hardware fasteners manufacturer with emphasis on industrial fastener supply, though no specific production equipment, capacity figures, or third-party verification is stated. The source description references state-of-the-art manufacturing capabilities and performance exceeding industry standards, but provides no measurable evidence or certification numbers to substantiate these claims. Buyers should treat such assertions as marketing language until validated by factory audit, sample testing, or documented quality agreements. Direct communication with the supplier is essential to confirm production lead times, minimum order quantities, and whether stock is held domestically in China or produced to order.
