Professional Applications & Engineering Value

These 12-24 UNC hex head screws are engineered to address common industrial fastening challenges, including vibration loosening and corrosion-induced failure. The steel construction with zinc plating provides a robust barrier against moisture and chemicals, making them ideal for outdoor equipment, machinery assembly, and structural applications. The coarse thread design ensures quick installation in various materials, while the external hex drive facilitates high clamping force with common wrenches. Their fully threaded 1" length offers consistent holding power, reducing the need for precise hole depth measurements in time-sensitive production environments.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit for consistent dimensional accuracy. These inch-system screws feature right-hand UNC coarse threads (12-24 size, 0.216" diameter) and meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements for safe use in industrial and consumer products.
