dacromet wheel bolts manufacturer
XZ Fastener manufactures Dacromet wheel bolts for automotive, trailer, truck, agricultural equipment, and wheel hub assemblies where corrosion resistance, thread accuracy, and seating geometry must be controlled. Wheel bolts can be supplied according to drawing, sample, thread size, shank length, seat type, head style, strength grade, Dacromet coating requirement, packaging, and inspection requirement. Common options include ball seat, cone seat, 12-point, hex head, flange head, and custom wheel bolts for aftermarket or OEM-style service kits. Bulk production can be reviewed with torque, thread gauge, coating thickness, and salt spray requirements.
Quick Specs
What Buyers Should Know Before Sourcing Dacromet Wheel Bolts
Wheel bolts are safety-related fasteners, so buyers should confirm both mechanical properties and assembly geometry before production. Thread diameter, pitch, thread length, shank length, under-head shape, seat angle or ball radius, head height, wrench size, and coating thickness can all affect wheel fit and tightening performance.
Before placing an order, provide the drawing, sample, mating wheel seat detail, hub thread requirement, material grade, heat treatment requirement, Dacromet coating target, torque requirement if available, and inspection method. Related fastener products can be reviewed when the same project also requires wheel nuts, washers, studs, or other coated hardware.

Material and Grade Explanation
Dacromet wheel bolts are often made from alloy steel or boron steel grades selected for strength, heat treatment response, and fatigue performance. Materials such as 40Cr, 35CrMo, 10B21, 4140, and SCM435 may be considered depending on the drawing, grade, thread size, and assembly requirement.
For custom wheel bolts, material grade should be confirmed together with heat treatment, hardness range, tensile requirement, proof load, seat geometry, and thread tolerance. Drawing-based projects can be reviewed through custom fasteners made to drawing, especially when the bolt must match an existing wheel, hub, or service kit design.
Surface Finish Selection Guide
Dacromet coating is often selected for wheel bolts when buyers need corrosion resistance with a thin coating profile. It can be used on high-strength fasteners where the coating process, baking, and hydrogen embrittlement risk should be reviewed carefully. Dacromet or zinc flake coating may be specified with a topcoat, color target, salt spray target, and coating thickness range.
For coated automotive and outdoor fasteners, buyers can compare Dacromet coated fasteners with zinc plating, hot dip galvanizing, black oxide, stainless steel, and other finishes. The corrosion resistance comparison can help clarify which finish is more suitable for storage, road exposure, humidity, or assembly conditions.
Manufacturing and Quality Control
Production may include wire or bar selection, cold heading or forging, machining for special geometry, thread rolling, heat treatment, surface preparation, Dacromet coating, curing, sorting, inspection, and packing. The route depends on head type, seat geometry, shank length, strength grade, finish requirement, and order quantity.
Common quality control points include thread gauge, thread length, seat angle or radius, head height, wrench size, shank diameter, hardness, tensile or proof load where specified, coating thickness, salt spray test where required, visual finish, and packing quantity. Buyers preparing inspection items can use the fastener quality inspection checklist before sending the final requirement.
