XZ Fastener supplies DIN 464 knurled thumb screws for wholesale buyers who need repeatable metric hand-operated screws, clear item separation, and practical packing for distributor or assembly stock. 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, label format, 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 review.
Quick Specs
What Buyers Should Know Before Sourcing DIN 464 Knurled Thumb Screws
DIN 464 knurled thumb screws are selected when the operator needs to tighten, loosen, or adjust a screw by hand. The knurled head is important because it affects grip, appearance, and user comfort. For wholesale programs, buyers should confirm thread diameter, screw length, head diameter, head height, end style, material, finish, packing unit, and label information before placing an order.
If your purchasing list includes companion parts, XZ Fastener can also review related fastener products such as nuts, washers, bolts, and special machined fasteners in one quotation request.
For distributor supply, the product is often ordered by metric size and finish, then packed into small bags, inner boxes, master cartons, or pallets. Buyer part numbers, barcode labels, carton marks, and mixed-size packing plans are available upon request.

Material and Grade Explanation
Carbon Steel
Carbon steel DIN 464 thumb screws are common for industrial equipment, fixtures, and general assemblies where cost control and reliable thread formation are important. Zinc plating, black oxide, or nickel plating can be supplied according to the working environment and appearance requirement.
Stainless Steel
Stainless steel A2 or A4 is often selected for humid areas, light chemical exposure, food-related equipment frames, outdoor cabinets, or assemblies where red rust must be reduced. Passivation and plain stainless finish options are available upon request.
Brass and Aluminum
Brass and aluminum thumb screws can be used where lower weight, electrical considerations, decorative appearance, or easy hand operation matters. These materials should be confirmed with drawing, application load, and mating thread material.
Strength Consideration
DIN 464 thumb screws are generally chosen for hand operation and adjustment, not for high-preload structural joints. For high-load assemblies, buyers may compare suitable high-strength fasteners with the design engineer before ordering.
Surface Finish Selection Guide
| Finish | Typical Use | Procurement Comment |
|---|---|---|
| Plain | Controlled indoor use, temporary assemblies, stainless steel supply | Protective packing may be needed to reduce handling marks. |
| Zinc Plated | General industrial equipment and distributor stock | Common for carbon steel thumb screws; color and salt spray expectations should be confirmed. |
| Nickel Plated | Visible assemblies, instruments, panels, display equipment | Often chosen for a cleaner appearance and smoother hand feel. |
| Black Oxide | Fixtures, machine tools, indoor mechanical parts | Oil protection 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 mixed finish sourcing, buyers can also check coated fasteners and send finish notes together with the DIN 464 size 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 surface finish appearance. For wholesale supply, packing accuracy is also important because distributors may receive many size and finish combinations in one shipment.
Buyers can use the DIN and ISO fastener standards guide as a reference when comparing standard dimensions, terminology, and purchasing descriptions across different metric fastener categories.
Common Checks Before Shipment
- Thread gauge and thread length confirmation
- Overall length and head dimension inspection
- Knurl consistency and burr control
- End style and chamfer confirmation
- Surface finish and visual sorting
- Carton quantity, label, and pallet mark verification
