For custom and replacement parts, XZ Fastener helps purchasing teams confirm manufacturability, critical dimensions, and production details before bulk ordering.
Common supply: made-to-drawing fasteners, sample-based parts, special threaded components, custom bolts, non-standard screws, and assembled hardware kits.
Quick Specs
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 supports non-standard fasteners and custom fasteners made to drawing 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.

Material and Grade Explanation
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 what should be included in a custom bolt drawing before sending an RFQ package.
Surface Finish Selection Guide
Zinc Plated
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.
Black Oxide or Phosphate
Common for machinery parts, socket screws, pins, and dark appearance hardware. Additional oil or rust prevention may be needed for storage and transport.
Hot Dip Galvanized
Often selected for outdoor structures, anchors, large bolts, and exposed assemblies. Thread allowance and matching nut fit should be checked before production.
Dacromet or Geomet
Useful for higher corrosion resistance with controlled coating thickness. These finishes can be considered for automotive, outdoor, and installation-sensitive parts.
Stainless Passivation
Applicable to stainless non standard fasteners where surface cleanliness and corrosion resistance are important. Passivation can be discussed when required.
Special Coatings
PTFE, nickel, chrome, zinc flake, color coating, or customer-specified surface treatment can be reviewed based on drawings and working conditions.
For coating selection, XZ Fastener provides a surface finish comparison chart for industrial fastener buyers.
Manufacturing and Quality Control
Non standard fastener manufacturing usually begins with drawing review, sample measurement, material selection, process planning, tooling confirmation, and sample approval. Depending on part geometry, XZ Fastener may use cold heading, hot forging, CNC machining, drilling, slotting, thread rolling, heat treatment, coating, sorting, and final packing.
Quality control may include raw material review, dimensional inspection, thread gauge inspection, hardness testing, tensile or proof load testing, coating thickness measurement, salt spray testing, surface appearance review, and assembly fit checking. Inspection scope can be arranged according to order requirement. Buyers can review XZ Fastener details on fastener quality control before confirming bulk production.
