العربية DIN 464 knurled thumb screws bulk order manufacturer
XZ Fastener manufactures DIN 464 knurled thumb screws for bulk orders where buyers need repeatable metric hand-operated screws, consistent knurled head dimensions, and practical packing for repeated assembly or distributor programs. The round knurled head provides grip for tool-free fastening and adjustment in instrument panels, machine covers, clamps, inspection doors, fixtures, electrical housings, display equipment, and maintenance assemblies. Material, thread size, head diameter, screw length, finish, carton quantity, pallet method, and inspection documents can be supplied according to order requirement. Buyers sourcing matching nuts, washers, or other fastener products can send one consolidated list for factory review.
Quick Specs
What Buyers Should Know Before Sourcing DIN 464 Knurled Thumb Screws
DIN 464 knurled thumb screws are used when a screw must be tightened, loosened, or adjusted by hand. The round knurled head affects grip, operator comfort, visual appearance, and assembly speed. For bulk orders, buyers should confirm thread diameter, screw length, head diameter, head height, end style, material, finish, carton weight limit, pallet method, and receiving label format before order confirmation.
If the purchasing list includes companion parts, XZ Fastener can review related fastener products such as nuts, washers, bolts, and custom machined fasteners in one factory quotation.
Bulk order planning should cover production batches, mixed-size packing, corrosion protection, scratch prevention, and warehouse handling. Buyer item numbers, carton marks, pallet labels, and inspection documents are available upon request.

Material and Grade Explanation
Carbon Steel
Carbon steel DIN 464 thumb screws are widely used for machinery, fixtures, covers, and general industrial assemblies. They can be supplied with zinc plating, black oxide, nickel plating, or other finish options according to the application environment and order requirement.
Stainless Steel
Stainless steel A2 or A4 is selected when corrosion resistance is more important, such as humid equipment rooms, outdoor cabinets, light chemical exposure, and assemblies where red rust must be reduced.
Brass and Aluminum
Brass and aluminum thumb screws may be used for light-duty equipment, instruments, electrical assemblies, or visible components where weight, appearance, or material compatibility matters. Drawings are recommended for bulk order confirmation.
Strength Consideration
DIN 464 thumb screws are mainly for hand operation and adjustment, not for high-preload structural fastening. For load-bearing assemblies, buyers may compare suitable high-strength fasteners with the project engineer before ordering.
Surface Finish Selection Guide
| Finish | Typical Use | Bulk Order Comment |
|---|---|---|
| Plain | Controlled indoor use, temporary assemblies, stainless steel supply | Protective packing may be needed to reduce surface marks during carton handling. |
| Zinc Plated | General industrial equipment and repeat assembly stock | Common for carbon steel; color, coating thickness, and corrosion expectation should be confirmed. |
| Nickel Plated | Visible assemblies, instruments, panels, display equipment | Often chosen for smoother appearance and cleaner hand contact. |
| Black Oxide | Fixtures, machine tools, indoor mechanical parts | Oil protection, individual separation, and packing method should be discussed for corrosion control. |
| Passivated Stainless | Stainless steel applications needing improved surface cleanliness | Suitable when stainless material is selected for corrosion resistance. |
For projects requiring mixed surface treatments, buyers can also review coated fasteners and send the finish requirement together with the DIN 464 bulk order list.
Manufacturing and Quality Control
Manufacturing control for DIN 464 knurled thumb screws focuses on stable thread dimensions, consistent head geometry, clean knurling, controlled end form, and acceptable surface finish. For bulk order manufacturing, packing accuracy and item separation are also important because one shipment may include many sizes, materials, and finishes.
Buyers can use the DIN and ISO fastener standards guide as a reference when comparing standard dimensions, descriptions, and purchasing terminology across metric fastener categories.
Common Checks Before Shipment
- Thread gauge and thread length confirmation
- Overall length, head diameter, and head height inspection
- Knurl consistency, grip surface, and burr control
- End style, chamfer, and contact surface confirmation
- Finish appearance and visual sorting
- Carton quantity, pallet marks, and packing list verification
Aplicaciones
Industrial Equipment
DIN 464 knurled thumb screws are used on machine covers, access panels, inspection doors, light guards, adjustment plates, and removable service parts where hand operation reduces maintenance time.
Electrical and Instrument Housings
They are suitable for electrical enclosures, meter boxes, test equipment, control panels, and display units where the head is visible and operators need grip without a tool.
Fixtures and Maintenance Assemblies
Knurled thumb screws can support repeated adjustment in jigs, fixtures, positioning devices, camera brackets, laboratory fixtures, and maintenance kits.
Custom Equipment Projects
When a project requires non-standard length, point shape, material, or packing, XZ Fastener can review drawings through its custom fasteners service.
