Русский made to order fasteners supplier
XZ Fastener supplies made to order fasteners for buyers who need controlled dimensions, materials, finishes, packaging, and inspection beyond standard catalog parts. Products can include bolts, screws, nuts, washers, threaded rods, anchors, inserts, spacers, pins, clamps, and assembled kits made from drawings, samples, or order specifications. Materials can be selected from carbon steel, alloy steel, stainless steel 304/316, brass, aluminum, and specified metals. For OEM and project purchasing teams, we help confirm thread fit, strength grade, coating requirements, marking, packing labels, and inspection points before production begins.
Quick Specs
What Buyers Should Know Before Sourcing Made to Order Fasteners
Made to order fasteners should be specified by function, not only by appearance. Buyers should confirm the drawing, sample, material grade, thread type, strength class, heat treatment, surface finish, mating parts, installation torque, tolerance, and packaging method before production. XZ Fastener can review drawings through its custom fastener service when the part has special geometry or must fit an existing assembly.
If the product is being reproduced from an old sample, photos and measurements are helpful, but they may not show material grade or heat treatment. The guide on drawing vs sample quotation explains when a drawing, sample, or both should be provided for a clearer manufacturing review.

Material and Grade Explanation
Material and grade should be selected according to working load, mating material, corrosion exposure, temperature, and installation method. Carbon steel is widely used for general fasteners and can be heat treated for higher strength. Alloy steel is often selected for high tensile bolts, socket screws, and heavy-duty assemblies. Stainless steel 304 is suitable for many corrosion-resistant applications, while 316 is often chosen for marine, chemical, and outdoor environments.
For drawing-based parts, buyers should specify material requirements clearly. XZ Fastener’s guide to made-to-drawing fastener material requirements can help purchasing teams decide what information should be written into drawings and purchase orders. Standard items can also be combined from the fastener products range.
Surface Finish Selection Guide
Zinc Plated
Suitable for indoor equipment, shelves, brackets, control cabinets, and general assembly. Blue-white zinc and yellow zinc can be supplied according to order requirement.
Black Oxide / Phosphate
Common for machinery, socket screws, tools, and assemblies that require a dark surface. Oil protection or anti-rust packing should be considered for storage.
Hot Dip Galvanized
Used for outdoor structures, solar mounting, guardrails, and construction projects. Nut fit or thread tolerance should be checked after galvanizing.
Dacromet / Geomet
Zinc flake coatings can be considered for corrosion resistance and lower hydrogen embrittlement risk in selected high-strength fastener applications.
Nickel / Chrome
Often used where a bright surface, wear resistance, or decorative appearance is needed. Cosmetic acceptance requirements should be confirmed before production.
PTFE
Often specified for stud bolts, nuts, and assemblies requiring corrosion protection and controlled friction. Color and thickness are available upon request.
For coating comparison by environment, service life, and thread fit, buyers can review the surface finish comparison chart before confirming the final finish.
Manufacturing and Quality Control
Made to order fastener production may involve material inspection, cutting, cold heading, hot forging, CNC machining, stamping, thread rolling, tapping, heat treatment, surface treatment, sorting, assembly, and packaging. The manufacturing route depends on part geometry, material, quantity, tolerance, and finish. For custom parts, XZ Fastener checks head shape, thread length, shank size, recess, washer face, hole position, chamfer, and coating allowance before production.
Quality control can include dimensional measurement, go/no-go thread gauge testing, hardness testing, tensile testing, coating thickness checks, visual inspection, and packing verification. Buyers can review the fastener quality control process when deciding which inspection items should be included in the purchase order.

How to Get a Faster Quotation
To receive a faster quotation, send the drawing, sample photo, standard number, size list, material grade, strength class, thread type, finish, quantity, packaging method, inspection requirements, and destination country. If several items are used in one assembly, send a BOM or project list with item numbers. The fastener drawings, samples, and RFQ checklist can help buyers prepare complete inquiry information.
If the part is still under design, include working load, mating parts, installation space, corrosion environment, and expected assembly method. For price and production review, buyers can also request a quote with files and project notes attached.
