XZ Fastener | Bulk Dacromet Coated Flange Fasteners
dacromet Flanschschrauben Großlieferant
XZ Fastener supplies Dacromet flange bolts in bulk for automotive, machinery, construction steelwork, equipment assembly, and outdoor fastening projects. Bulk buyers can source serrated or non-serrated flange bolts according to standard, drawing, material grade, thread size, coating thickness, packing method, and inspection requirement. Flange bolts combine a hex drive head with an integrated washer face, helping distribute load and reduce separate washer handling in suitable assemblies. Dacromet coating is often selected for corrosion resistance and lower hydrogen embrittlement concern compared with many electroplated finishes. Custom dimensions and export packaging can be supplied upon request.
Kurzspezifikationen
What Buyers Should Know Before Sourcing Dacromet Flange Bolts
Dacromet flange bolts should be purchased with clear information on flange diameter, bearing surface type, thread pitch, thread length, head dimensions, strength class, coating requirement, packing requirement, and mating part design. Serrated flange bolts can provide extra resistance to loosening, while non-serrated flange bolts are often preferred when the mating surface must not be marked. For a wider comparison of flange bolt use cases, buyers can review XZ Fastener’s flange bolt buying considerations.
For bulk sourcing, packaging and inspection details should be confirmed before production. Carton weight, pallet dimensions, label format, barcode requirement, and batch traceability can affect handling cost and warehouse efficiency. Buyers should also confirm whether the bolt is used against steel, coated parts, aluminum, slotted holes, or a bracket surface.

Material- und Sortenerklärung
Flange bolts are frequently used where assembly speed, bearing surface control, and vibration resistance matter. Carbon steel can be used for lower or moderate duty fastening, while medium carbon steel and alloy steel are often selected for grade 8.8, 10.9, and 12.9 flange bolts. The correct choice depends on clamp load, mating material, service environment, and whether the bolt is used in automotive, structural, or machinery applications.
For high tensile flange bolts, heat treatment and thread quality should be controlled carefully. Buyers should state the required grade, test method, and whether the flange face must be serrated or smooth. For assemblies exposed to weather, coating performance should be discussed together with grade and torque requirements.
Leitfaden zur Auswahl der Oberflächenbeschaffenheit
Dacromet is a zinc-aluminum flake coating often used when buyers need corrosion resistance on high strength fasteners. It is not an electrolytic coating, which makes it a practical option for many high tensile bolt projects. Buyers comparing finishes can review XZ Fastener’s Dacromet coated bolts Informationen und die Leitfaden zur Beschichtung von Verbindungselementen before confirming the specification.
Surface finish should be selected with the whole assembly in mind. A flange bolt may contact painted steel, galvanized steel, aluminum, or another coated component. To avoid assembly issues, confirm coating thickness, friction coefficient, thread fit, storage conditions, and corrosion test requirement before placing the order.

Anwendungen
Dacromet flange bolts are used in automotive brackets, chassis components, machinery frames, outdoor equipment, construction connections, guardrail systems, agricultural machinery, and general industrial assemblies. The integrated flange helps distribute pressure under the head and can reduce the need for a separate washer in suitable designs. Serrated flange bolts are often selected for vibration-prone assemblies, while non-serrated flange bolts are used where the surface should remain less marked.

FAQ
Can XZ Fastener supply Dacromet flange bolts for bulk orders?
Yes. Dacromet flange bolts can be supplied for bulk purchasing according to drawing, sample, or detailed specification. Please provide thread size, length, flange diameter, serrated or non-serrated face, strength class, coating requirement, quantity, and packing details.
Was ist der Unterschied zwischen gezahnten und nicht gezahnten Flanschschrauben?
Serrated flange bolts have teeth under the flange to improve resistance to loosening, while non-serrated flange bolts have a smoother bearing face that is usually better when the mating surface should not be marked.
Is Dacromet suitable for grade 10.9 flange bolts?
Dacromet wird häufig für hochfeste Verbindungselemente verwendet, da es sich um eine nicht elektrolytische Zink-Aluminium-Lamellenbeschichtung handelt. Die endgültige Eignung hängt von der Sorte, den Beschichtungsspezifikationen, den Reibungsanforderungen und der Betriebsumgebung ab.
Können Anforderungen an die Beschichtungsdicke und den Salzsprühtest festgelegt werden?
Ja. Beschichtungsdicke, erwartete Korrosionstests, Farbton und damit verbundene Prüfanforderungen können vor der Auftragsbestätigung besprochen werden. Diese Anforderungen sollten im RFQ oder in den Zeichnungsnotizen klar angegeben werden.
Can Dacromet flange bolts be packed for warehouse distribution?
Yes. Bulk carton, inner box, small box, pallet, label, barcode, and buyer-specific export packing can be arranged according to order requirement. Please provide carton weight limits, pallet dimensions, and label format if required.
Can XZ Fastener supply matching nuts or washers with flange bolts?
Passende Muttern, Unterlegscheiben, Sechskantbolzen, Gewindestangen und andere beschichtete Verbindungselemente können im Rahmen eines Beschaffungsprojekts besprochen werden. Beim Zusammenbau der Teile sollten Passgenauigkeit und Gewindepassung gemeinsam bestätigt werden.
