Key Features & Benefits at a Glance
- Tamper-resistant Torx T10 drive prevents unauthorized removal, enhancing security in public or restricted-access installations.
- 18-8 Stainless Steel with passivated finish provides superior corrosion resistance, ensuring long-term durability in harsh environments.
- Integrated Buna-N rubber O-ring creates a reliable seal, capable of withstanding up to 1500 psi maximum pressure for leak-proof assemblies.
- Class 3A UNC coarse thread delivers precise, high-strength fastening with excellent vibration resistance in industrial applications.
- Wide temperature tolerance (-40° to 225°F) allows consistent performance in extreme thermal conditions without seal degradation.
- Fully threaded design maximizes grip length and load distribution for enhanced joint integrity.
- Compliance with ASME B18.3, RoHS 3, and REACH ensures adherence to rigorous industrial and environmental standards.
Professional Applications & Engineering Value
This 6-32 x 1/2" rounded head screw combines 18-8 stainless steel construction with a passivated finish to solve critical challenges in corrosive or high-moisture environments. The tamper-resistant Torx drive addresses security concerns in public infrastructure, while the Buna-N O-ring sealing effectively prevents fluid ingress in pressurized systems up to 1500 psi. Its Class 3A UNC coarse threads provide superior thread engagement and vibration resistance, making it ideal for machinery, electronic enclosures, and automotive assemblies where reliability under stress is paramount. The fully threaded design ensures uniform stress distribution, reducing the risk of joint failure in dynamic load conditions.
Specification Summary & Compliance
This screw features Class 3A thread fit with UNC coarse threading (6-32 size) and dimensional compliance with ASME B18.3 standards. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial use. The maximum hole diameter is 0.151" with a tensile strength of 70,000 psi, ensuring high mechanical performance in demanding applications.
