Русский DIN 464 knurled thumb screws factory
XZ Fastener manufactures DIN 464 knurled thumb screws for buyers who need metric hand-operated screws with a round knurled head for grip, adjustment, and tool-free fastening. These screws are used in instrument panels, machine covers, clamps, inspection doors, fixtures, electrical housings, display equipment, and maintenance assemblies where repeated manual operation is expected. Material, thread size, head diameter, screw length, finish, packing method, and inspection documents can be supplied according to order requirement. Buyers sourcing matching nuts, washers, or other fastener products can send one size list for factory review.
Quick Specs
What Buyers Should Know Before Sourcing DIN 464 Knurled Thumb Screws
DIN 464 knurled thumb screws are selected when users need direct hand grip for frequent adjustment or removal. Buyers should confirm thread size, pitch, screw length, head diameter, head height, knurl pattern, end style, material, finish, and whether the screw is visible on the finished equipment.
Thumb screws are usually not intended for high preload joints. For assemblies that also need nuts, washers, or industrial bolts, XZ Fastener can review related items together so thread, material, appearance, and packing are consistent across the order.
Factory Sourcing Notes
- Confirm whether the knurled head should follow standard DIN 464 dimensions or a buyer drawing.
- State whether the head surface is handled frequently, because burr control and finish smoothness matter.
- Check whether the screw end needs flat, chamfered, dog point, or other drawing-specific treatment.
- Send drawings when head diameter, knurl form, thread length, or appearance has special requirements.
Common Purchasing Descriptions
- DIN 464 knurled thumb screws, carbon steel, zinc plated, metric thread, carton packing.

Material and Grade Explanation
Carbon Steel
Carbon steel DIN 464 knurled thumb screws are common for equipment covers, fixtures, clamps, and general machinery assemblies. Zinc plating or black oxide can be selected according to appearance and corrosion needs.
Stainless Steel
Stainless steel options can be supplied for humid environments, exposed equipment, and assemblies requiring better corrosion resistance. A2 or A4 should be selected according to the working environment.
Brass, Aluminum, or Custom Materials
Brass and aluminum can be reviewed for electrical, decorative, or lightweight assemblies. Special head forms or end styles can be discussed through XZ Fastener’s custom fasteners service.
Surface Finish Selection Guide
Zinc Plated
Zinc plated DIN 464 knurled thumb screws are widely used for clean appearance and general indoor corrosion protection. Buyers should confirm color, coating thickness, and surface smoothness.
Nickel Plated or Stainless
Nickel plated or stainless options can be selected when the thumb screw is visible or handled frequently and a brighter, cleaner appearance is required.
Black Oxide
Black oxide can be selected for indoor equipment, fixtures, and instruments requiring a dark finish. Oiling, packing, and corrosion expectations should be confirmed before production.
For assemblies requiring the same finish across screws, nuts, bolts, and washers, related coated fasteners can be reviewed together before quotation.
Manufacturing and Quality Control
Manufacturing control for DIN 464 knurled thumb screws focuses on thread accuracy, screw length, head diameter, head height, knurl consistency, end style, surface condition, coating coverage, and packing separation. Since thumb screws are operated by hand, burr control and head finish are important for user comfort and product appearance.
When the order includes matching nuts, washers, or high-strength fasteners, buyers should confirm whether a hand-operated thumb screw is suitable for the intended joint load and repeated use.
Common Control Points
- Thread go/no-go gauge checks according to agreed tolerance.
- Head diameter, knurl form, length, and end-style checks.
- Visual inspection for burrs, cracks, rust, coating defects, and rough edges.
- Carton quantity, scratch prevention, label, and mixed-size prevention checks before shipment.
تطبيقات
For buyers comparing DIN 464 with other metric screw standards, the DIN and ISO fastener standards guide may help organize standards, drawings, and purchasing descriptions before inquiry.
How to Get a Faster Quotation
- Send DIN standard, thread size, screw length, material, finish, and quantity per size.
- Confirm head diameter, head height, knurl form, end style, and any appearance requirement.
- State packaging needs, including bulk carton, inner box, bag quantity, scratch protection, label, and pallet method.
