What Buyers Should Know Before Sourcing Non Standard Fasteners
Non standard fasteners are usually required when a standard catalog item cannot meet the shape, load, installation space, thread, coating, or assembly requirement. Before requesting production, buyers should prepare the drawing revision, material grade, heat treatment requirement, critical tolerances, thread standard, surface finish, inspection points, and packaging rules.
XZ Fastener 支持 non-standard fasteners 和 按图纸制作的定制紧固件 for OEM, project, and distributor orders. When a drawing is not available, samples or clear photos can help the technical team review possible production methods.
- Confirm whether the part should be cold headed, hot forged, CNC machined, bent, stamped, drilled, slotted, or assembled.
- Identify critical dimensions such as head height, shank diameter, thread length, hole position, shoulder length, and bearing surface.
- State whether the part is load-bearing, corrosion-exposed, appearance-sensitive, installation-sensitive, or used in repeated maintenance.
- Check coating thickness carefully when the thread fit or mating nut clearance is tight.
- For unclear samples, review the guide on reverse engineering custom fasteners from samples.

材质及牌号说明
Carbon steel is commonly used for non standard bolts, screws, washers, and brackets when strength, forming performance, and cost control are important. Alloy steel can be selected for high-strength parts, while heat treatment and thread rolling should be planned together to meet mechanical requirements.
Stainless steel 304 and 316 are suitable for corrosion-resistant parts, while brass, aluminum, copper, and titanium may be used for electrical, decorative, lightweight, or specialty applications. For non standard parts, buyers should specify material grade, hardness or tensile requirement, surface condition, and any critical chemical or mechanical requirement.
For drawing preparation, buyers can review 定制螺栓图中应包含哪些内容 before sending an RFQ package.
表面处理选择指南
镀锌
Suitable for many carbon steel non standard fasteners used indoors or in moderate environments. Blue white zinc, clear zinc, and yellow zinc can be supplied according to order requirement.
黑色氧化物或磷酸盐
Common for machinery parts, socket screws, pins, and dark appearance hardware. Additional oil or rust prevention may be needed for storage and transport.
热镀锌
通常选择用于室外结构、锚、大型螺栓和裸露组件。生产前应检查螺纹余量和配套螺母的配合情况。
达克罗或吉美特
Useful for higher corrosion resistance with controlled coating thickness. These finishes can be considered for automotive, outdoor, and installation-sensitive parts.
不锈钢钝化
Applicable to stainless non standard fasteners where surface cleanliness and corrosion resistance are important. Passivation can be discussed when required.
