S-92941A542 1/4"-20 x 1" ASME B18.2.1 Brass Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to brass construction, ideal for harsh environments and long-term reliability.
• High tensile strength of 50,000 psi ensures secure, durable fastening for demanding industrial applications.
• Rockwell B55 hardness provides excellent wear resistance and prevents thread deformation during installation.
• Class 2A thread fit with UNC coarse threading offers easier, faster assembly and reduced risk of cross-threading.
• External hex drive and hex head design allows for high-torque application with standard tools, speeding up installation.
• Full threading along the 1" length maximizes grip and load distribution across the entire fastener.
• Compliance with ASME B18.2.1, RoHS 3, and REACH guarantees consistent quality, safety, and environmental responsibility.

Professional Applications & Engineering Value

Engineered for reliability, these 1/4"-20 UNC brass hex head screws solve critical challenges in electrical, marine, and plumbing systems where corrosion resistance is paramount. The brass material naturally resists oxidation and galvanic corrosion, extending service life in humid or chemically aggressive settings. With a coarse thread and Class 2A fit, these screws provide quick, secure fastening even in vibration-prone assemblies, reducing installation time and maintenance needs. The external hex drive ensures compatibility with common wrenches, facilitating high-torque tightening without slippage. Ideal for securing panels, connectors, and machinery components, these fully threaded screws deliver consistent clamping force, enhancing structural integrity in industrial applications.

Specification Summary & Compliance

This screw features a 1/4"-20 UNC thread with Class 2A dimensional accuracy for reliable fit. It is manufactured to meet ASME B18.2.1 standards, ensuring consistent geometry and performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms adherence to environmental and safety regulations, with no restricted substances. The fully threaded design and specified dimensions (e.g., 1" length, 7/16" head width) support precise application requirements.
