It can be applied to carbon steel and alloy steel fasteners according to order requirement, including DIN, ISO, ASTM, ASME, and drawing-based parts. Send size list, grade, coating target, quantity, packaging, and inspection requirements to receive a practical quotation.
Useful RFQ details include standard, dimensions, grade, coating color, salt spray target, matching parts, packing format, and required inspection documents.
Quick Specs
What Buyers Should Know Before Sourcing Geomet Coated Fasteners
Geomet coated fasteners are typically chosen when corrosion resistance, coating thickness control, and assembly performance matter together. Compared with hot dip galvanizing, zinc flake coatings usually have lower coating build-up, which can help maintain thread fit on bolts, nuts, and screws. Compared with some electroplated finishes, they are often reviewed for high-strength parts where hydrogen embrittlement risk is a concern.
XZ Fastener can quote standard metric hex head bolts, screws, nuts, washers, and custom fasteners with Geomet-type coating. Buyers comparing similar finishes can also review Dacromet coated fasteners before confirming the coating system.
Procurement Notes
- Confirm whether the order requires a specific zinc flake system, color, topcoat, or friction range.
- Specify salt spray target, coating thickness, and sample approval requirements before production.
- For high-strength fasteners, review material grade, heat treatment, and coating process together.
- When supplied as assemblies, match coating requirements across bolts, nuts, washers, and screws.

Detailed Specifications Table
| Artículo | Common Options | Buyer Confirmation Points |
|---|---|---|
| Product types | Hex bolts, flange bolts, socket screws, self-tapping screws, nuts, washers, threaded rods, custom fasteners | Confirm part type, standard, drawing, and whether items are supplied individually or as assemblies. |
| Estándares | DIN, ISO, ASTM, ASME, EN, JIS, or customer drawing | Send the exact standard or drawing revision used in the purchase order. |
| Size range | Metric and inch sizes can be reviewed according to order requirement | Provide diameter, length, pitch, thread length, and quantity for each line item. |
| Thread | Metric coarse, metric fine, UNC, UNF, tapping screw thread, or custom thread | Confirm thread tolerance and mating parts because coating can affect final assembly feel. |
| Material | Carbon steel, medium carbon steel, alloy steel, or specified material | Confirm material grade and heat treatment requirement for high-strength or critical fasteners. |
| Fuerza | 4.8, 8.8, 10.9, 12.9, ASTM grades, or drawing-specified strength | Match bolt, nut, and washer grades when parts are used as an assembly. |
| Coating | Geomet-type zinc flake coating with optional topcoat where specified | Confirm color, salt spray target, coating thickness, and friction requirement if applicable. |
| Inspection | Dimension, thread gauge, coating appearance, thickness, hardness, tensile, salt spray when required | Inspection reports and sample approval should be agreed before production. |
Material and Grade Explanation
Geomet coated fasteners are commonly produced from carbon steel or alloy steel. The base material provides mechanical strength, while the zinc flake coating improves corrosion resistance. Grade 8.8 carbon steel hex bolts are common for general machinery and construction hardware, while 10.9 and 12.9 fasteners may be selected for higher clamp load applications.
For high-strength items, buyers should review the full production route, including heat treatment, thread rolling, coating process, and inspection. The coating choice should match the assembly environment and tightening method, especially where torque control, preload, or vibration resistance is important.
Grade Selection Tips
- Use 4.8 or 8.8 when general fastening strength is sufficient.
- Use 10.9 or 12.9 only after confirming mating material, load, and tightening method.
- For bolt-nut-washer assemblies, specify every component grade and finish together.
- Request test requirements before production if the parts are used in critical equipment.
Surface Finish Selection Guide
Geomet / Zinc Flake
Geomet-type zinc flake coating is often used when corrosion resistance, controlled coating build-up, and high-strength fastener compatibility are required. Buyers can review broader coating options in the fastener coating guide.
Zinc Plated and Black Oxide
Zinc plating is often used for indoor or light-duty corrosion protection, while black oxide is mainly selected for dark appearance and controlled indoor use. These finishes may be suitable when salt spray and outdoor exposure requirements are lower.
Hot Dip Galvanized
Hot dip galvanizing creates a thicker zinc layer for outdoor steelwork, but coating build-up can affect thread fit more than zinc flake finishes. The corrosion resistance comparison guide helps buyers compare common finish choices.
Manufacturing and Quality Control
Production can include raw material preparation, forming or machining, thread rolling or tapping, heat treatment where required, cleaning, coating preparation, zinc flake coating, curing, inspection, and packing. For coated fasteners, key control points include dimensions before coating, thread fit after coating, coating coverage, surface appearance, batch separation, and packaging that protects the finish during shipment.
Inspection can be arranged according to order requirement, including dimensional checks, go/no-go thread gauge testing, coating review, thickness checks, hardness testing, and salt spray testing when specified. Buyers can also review coating inspection requirements and the XZ Fastener quality control process before confirming inspection terms.
Aplicaciones

- Protect coated parts from abrasion during packing and shipment.
- Store fasteners in a dry area before installation to preserve surface condition.
How to Get a Faster Quotation
Send a complete RFQ with product type, standard, size list, thread pitch, material, strength class, Geomet coating requirement, salt spray target if any, color or topcoat requirement, quantity, packaging method, delivery destination, and inspection requirements. If the parts must meet an existing assembly specification, include drawings, photos, or sample references.

Yes. Geomet coated fasteners can be reviewed for bolts, nuts, washers, screws, threaded rods, and custom parts according to size, grade, coating, packaging, and inspection requirements.
What is Geomet coating used for?
Geomet-type zinc flake coating is commonly used for corrosion-resistant fasteners in automotive, machinery, solar mounting, outdoor equipment, and humid or salt-exposed environments.
Is Geomet coating the same as hot dip galvanizing?
No. Hot dip galvanizing creates a thicker zinc coating, while Geomet is a zinc flake coating system. The right choice depends on corrosion target, thread fit, friction requirement, and application environment.
Can high-strength fasteners be supplied with Geomet coating?
High-strength fasteners can be reviewed with Geomet-type coating. Buyers should confirm grade, coating requirement, hydrogen embrittlement concerns, friction requirement, and inspection standards before production.
Can salt spray testing be arranged for Geomet coated fasteners?
Salt spray testing can be arranged when required by the order. Buyers should specify target hours, test standard, sample quantity, and whether a report is required before shipment.
What information is needed for a Geomet coated fastener quotation?
Please send the size list, standards, material, grade, coating requirement, quantity, packaging method, delivery destination, matching parts, and inspection requirements. Drawings are recommended for non-standard items.
