中国拖拉机车轮螺栓供应商
XZ Fastener supplies tractor wheel bolts from China for agricultural machinery OEMs, replacement parts distributors, farm equipment repair teams and heavy vehicle hardware importers. Wheel bolts are used on hubs, rims, axle assemblies and service kits where clamping force, thread fit, seat geometry and fatigue resistance must be controlled. Orders can be supplied according to drawings, samples or size lists, including matched wheel nuts and washers when required. Buyers can specify material grade, finish, quantity, packing method and inspection documents according to order requirement.

What Buyers Should Know Before Sourcing Tractor Wheel Bolts
Tractor wheel bolts should be specified by more than diameter and length. Wheel seat angle, head style, shank fit, thread pitch, nut compatibility and tightening practice all affect whether the wheel assembly holds preload during field use. Agricultural equipment can face mud, vibration, side load, impact and repeated wheel removal, so the bolt should match both the rim and hub design.
Before production, buyers should confirm whether the part is a wheel bolt, wheel stud, hub bolt or rim bolt. For dynamic equipment connections, the guide to 抗冲击和振动的紧固件 is useful when preparing technical requirements.

材质及牌号说明
Tractor wheel bolts normally use carbon steel or alloy steel with controlled heat treatment. Grade 8.8 may be suitable for general machinery hardware, while wheel applications often require higher clamp load, better fatigue resistance and stable hardness. Buyers should confirm the tractor model, wheel load, rim thickness and tightening method before choosing grade.
For farm vehicles and heavy equipment, material selection should consider shock load, corrosion exposure and service replacement interval. XZ Fastener also supports made-to-drawing requirements for 车辆紧固件材料 when the wheel bolt specification includes special mechanical or coating needs.
表面处理选择指南
Tractor wheel bolts may be supplied in plain, oil black, black oxide, zinc plated, hot dip galvanized, Dacromet or Geomet finish according to order requirement. Plain and oil black finishes are often used for protected or quickly installed parts. Zinc plating supports moderate storage and corrosion protection. Dacromet or Geomet may be selected where corrosion resistance is requested without excessive thread build-up.
When wheel bolts and nuts are supplied together, finish compatibility and thread fit should be checked as one assembly. Buyers can compare coating choices in the 表面光洁度选择指南.

如何获得更快的报价
For tractor wheel bolts, send a size list with diameter, total length, thread length, thread pitch, head style, seat type, shoulder dimension, material grade, finish, quantity and matched nut requirement. If available, include the tractor model, rim photo, sample photo or drawing. This helps confirm whether a standard wheel bolt can be supplied or whether custom production is needed.
For distributor and repair kit orders, include packaging quantity per set, carton weight, label format, pallet requirement and inspection documents. If tightening control is part of the application, the 螺栓扭矩和预紧力指南 can help align technical details before purchasing.
