S-94063A338 M6 x 16 mm Tamper-Resistant Drilled Spanner Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• High mechanical strength offering 80,000 psi tensile strength and Rockwell B96 hardness for demanding load-bearing applications.
• Secure and tamper-resistant fastening via the drilled spanner drive, providing a positive grip and reducing the risk of stripping.
• Precise and reliable thread engagement with a Class 6g thread fit and fully threaded design for consistent clamping force.
• Easy installation and flush finish thanks to the standard 90° flat head profile, which sits neatly in countersunk holes.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safe use in industrial and consumer goods.
• Durable surface protection from the passivated finish, enhancing corrosion resistance and extending service life.

Professional Applications & Engineering Value

These M6 flat head screws are engineered to address critical challenges in machinery assembly, electronic enclosures, and structural frameworks where flush mounting and high tensile strength are paramount. The 18-8 stainless steel material ensures excellent resistance to oxidation and chemical exposure, reducing maintenance in corrosive settings. The drilled spanner drive offers a secure, low-profile fastening solution, minimizing the risk of cam-out during installation. With a fully threaded metric coarse thread (M6x1mm), these screws provide superior holding power in metals and plastics, making them ideal for industrial fasteners requiring vibration resistance and long-term integrity under stress.

Specification Summary & Compliance

This screw meets precise dimensional standards, including a Class 6g thread fit per metric specifications, ensuring interchangeability and reliable performance. The head diameter tolerance is controlled between -0.41 to 0 mm for consistent countersinking. Manufacturing adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming the absence of restricted hazardous substances for safe industrial and commercial use.
