Threaded to 10-32 UNF specifications, it measures 2.5 inches under the head and accepts a 5\/32-inch hex key drive. The screw is manufactured from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection on the fastener surface. It is partially threaded along its shank length. This fastener meets ASME B18.3 and ASTM A574 dimensional and mechanical standards, making it suitable for precision assemblies, machine components, and structural joints where controlled thread engagement is critical.\u003c\/p\u003e\n\u003cp\u003eThis screw is used across a wide range of trade and industrial applications, including HVAC equipment assembly, electrical panel and enclosure fabrication, plumbing fixture mounting, and general mechanical assembly. The 10-32 UNF thread is common in light-gauge metal assemblies and equipment housings where fine-thread engagement is preferred for improved holding strength and resistance to vibration loosening. The black oxide finish makes it a practical choice in applications where the fastener will be exposed to occasional moisture but does not require heavy-duty corrosion protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-32 UNF thread provides fine-pitch engagement for vibration-resistant fastening\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head accommodates moderate material stack thicknesses\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for use with standard Allen or hex key wrenches\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers moderate corrosion resistance in controlled environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for precise clamping and alignment in through-bolt applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-use fastener for assemblies requiring 10-32 UNF hex socket cap screws conforming to ASME B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/32-inch hex key or Allen wrench; use a calibrated torque wrench when the application specifies a torque value. Ensure the mating threaded hole is clean and free of debris before driving the screw. Do not exceed the rated mechanical limits defined by ASTM A574 for this thread size and material grade.
