Product Overview
The PEEK DIN 912 Socket Head Cap Screw is a precision-machined high-performance polymer fastener delivering the strength of a standard socket cap screw combined with PEEK’s unmatched chemical inertness, thermal endurance, and ultra-low outgassing. Conforming to DIN 912 dimensional standards, it features a cylindrical head with hexagon socket drive — the workhorse fastener for semiconductor wafer fabrication equipment, vacuum chambers, wet process tools, and high-purity fluid handling systems.
Semiconductor-Grade Performance
- Plasma Etch Chamber Compatible — Resists aggressive fluorine and chlorine-based plasma environments. Suitable for RIE, ICP, and ALD/ALE chamber fixturing.
- Wet Chemistry Resistance — Impervious to standard clean (SC-1/SC-2), piranha etch (H₂SO₄:H₂O₂), buffered oxide etch (BOE), and solvent strips (NMP, acetone, IPA).
- High-Temperature Endurance — Maintains mechanical integrity at 260°C continuous operation. Handles bake-out cycles, diffusion furnace peripherals, and rapid thermal processing (RTP) environments.
- Zero Metal Contamination — Full polymer construction eliminates Fe, Cu, Ni, and Cr contamination risks in front-end processes. Ideal for ion implant end-stations and epitaxial growth reactors.
- Low Outgassing (ASTM E595) — TML < 0.1%, CVCM < 0.01%. Suitable for ultra-high vacuum (UHV) applications and space simulation chambers.
- Electrical Isolation — Dielectric strength > 20 kV/mm. Prevents stray currents in wafer chuck assemblies, ESC (electrostatic chuck) mounts, and RF-biased electrode fixtures.
