Electro Hardware MTHS3009M07L14m Ss Thumb Screw M3.5x0.6

Product Description

The ELECTRO HARDWARE MTHS3009M07L14m is a 303 stainless steel thumb screw with a knurled head, designed for hand-tightening applications where tools are not required. Featuring a metric M3.5 x 0.6 thread and an overall length of 14 mm, this fastener provides reliable clamping without the need for a wrench or driver. The 8 mm knurled head diameter gives a secure grip, and the 5 mm head height keeps the profile low. Manufactured from 303 stainless steel with an uncoated finish, it delivers good corrosion resistance and machinability. It is installed by technicians and assemblers working in instrumentation, panel fabrication, enclosure assembly, and light mechanical applications.

This thumb screw is suited for applications requiring frequent hand adjustment or tool-free access. Common uses include equipment panels, junction enclosures, inspection covers, and light fixtures where repeated removal and reinstallation are expected. The metric thread standard and QQ-S-763 compliance make it appropriate for both commercial and industrial assembly environments requiring dimensional consistency and material traceability.

Key Features

• 303 stainless steel construction provides corrosion resistance in moderate environments
• M3.5 x 0.6 metric thread for precise engagement in tapped metric holes
• Knurled head allows secure hand-tightening without tools
• 14 mm overall length with an 8 mm head diameter and 5 mm head height
• No shoulder design for straightforward through-hole or tapped-hole installation
• Meets QQ-S-763 material standard for stainless steel fasteners

Compatibility

Designed as an OEM-style replacement or standard metric fastener for equipment panels, enclosures, and assemblies requiring an M3.5 x 0.6 metric thread thumb screw without a shoulder.

Installation Notes

This thumb screw is installed by hand into a pre-tapped M3.5 x 0.6 metric hole. Verify thread engagement depth against the 14 mm overall length before installation to avoid bottoming out in blind holes. Do not use power tools to drive knurled-head thumb screws, as over-torquing can strip threads or crack the knurled head. Follow applicable assembly specifications for torque limits when hand-tightening is not sufficient for the application.
