Type of Screw Material
  • Low Carbon Cold Heading Steel (4.8 / 6.8 Grade Screws, Self-tapping Screws),excellent cold forming performance, no heat treatment required, cost-effective, widely used for general. Like SAE(1008、1010、1018), JIS SWRCH18A.
  • Medium Carbon Steel (8.8 Grade Fasteners) Stable hardness after quenching and tempering, good mechanical strength, ideal for standard structural bolts. Like 35#,45#.
  • Boron Alloy Steel (8.8 / 9.8 Grade Economy Fasteners) Superior cold forming performance, low cracking rate, cost-efficient high-strength material for mass production. Like 10B21,10B33.
  • Chrome / Chrome-Moly Alloy Steel (10.9 / 12.9 Grade High-Strength Fasteners),Ultra-high tensile strength, excellent fatigue resistance, high temperature and pressure resistance, for heavy-duty industrial applications.Like 40Cr, 35CrMo.
  • Stainless Steel (Corrosion-Resistant Fasteners),Rust-proof, acid and alkali resistant, high durability, suitable for outdoor, kitchen, bathroom and electronic precision scenarios. Like SUS304, SUS316, SUS316L, SUS303, SUS410.
  • Copper & Brass  (Conductive & Sealing Fasteners),High electrical conductivity, good ductility, excellent cutting and forming performance. Like H62, H65, H68.
  • Aluminum  (Lightweight Fasteners),Ultra-light, oxidation-resistant, widely used in new energy and home appliance products. Like 6061,6063.

GD Fastenal maintain flexible MOQ policies for customized fastener projects to support both prototype development and mass production. For standard custom screw sizes and common materials, we accept low-volume trial orders to accommodate clients’ initial testing and small-batch demands. For fully non-standard shapes that require new tooling, the MOQ is based on tooling costs and production feasibility. Usually MOQ10000pcs custom made screw.

Yes, GD Fastenal fully support custom manufacturing according to customer-provided 2D and 3D design files. Our engineering team can process and analyze multiple mainstream file formats, including PDF, DWG, STEP, and IGS. We conduct detailed technical reviews, dimensional verification, and manufacturability evaluations before tooling and production to ensure every custom fastener strictly matches your design specifications and functional requirements.

GD Fastenal implement strict full-process quality control for all non-standard and custom screws to eliminate dimensional defects and ensure stable performance. All custom fasteners undergo 100% optical sorting inspection to screen out flaws such as wrong thread size, uneven head tolerance, burrs, and surface defects. In addition, we can provide official Material Test Reports (MTR), heat treatment certificates, and surface finishing inspection reports upon request, fully supporting customer quality audits and project compliance requirements.

For outdoor facilities and electric vehicle (EV) charging pile applications that require long-term weather resistance, anti-rust performance, and environmental durability, SUS304 and SUS316 stainless steel are the most ideal material choices. SUS304 provides excellent general corrosion resistance, effectively resisting oxidation, rainwater erosion, and daily outdoor aging, making it cost-effective for most outdoor installation scenarios. SUS316 offers upgraded marine-grade anti-corrosion performance with molybdenum elements added, delivering superior tolerance against salt spray, humid climates, and industrial corrosive environments, which ensures long-term stable operation and low maintenance rates for EV charging piles and outdoor equipment.
