Kipp K0140.04X10 M4 Knurled Steel Thumb Screw Black Oxide

Product Description

The KIPP K0140.04X10 is a knurled head thumb screw machined from 1.0718 grade steel with a black oxide finish. It features an M4 metric thread, a shouldered shank, and a flat tip, making it well-suited for manual fastening applications where tools are not required or practical. The knurled head measures 0.6299 inches in diameter and 0.1378 inches in height, providing a secure grip surface. Overall length is 0.7677 inches. This thumb screw conforms to DIN 464, a widely recognized standard for knurled-head screws in industrial and mechanical assemblies.

This thumb screw is used in light industrial, mechanical, and instrumentation applications where frequent manual adjustment or removal is needed. The shouldered design helps locate and retain mating components accurately. The black oxide finish provides mild corrosion resistance suitable for indoor or controlled environments. Maintenance technicians, mechanical assemblers, and equipment builders typically work with this hardware in panel, fixture, and enclosure applications.

Key Features

• M4 metric thread for compatibility with standard metric tapped holes
• Knurled head design allows tool-free hand tightening and loosening
• With-shoulder configuration for accurate component location
• Black oxide finish on 1.0718 steel for mild corrosion resistance
• Flat tip for clean contact against mating surfaces
• Conforms to DIN 464 standard

Compatibility

Designed as a DIN 464-compliant M4 knurled thumb screw suitable for metric-threaded assemblies requiring manual fastening with a shouldered, flat-tip configuration.

Installation Notes

Install and remove by hand; no tools are required for standard applications. Ensure the mating tapped hole is clean and free of debris before threading in. Do not overtighten, as excessive hand force may damage the thread engagement in softer mating materials. This hardware is intended for indoor or protected environments given the black oxide surface treatment.
