Diversitech 6641 Hex Head Cap Screws 3/8 Inches 16 Thread 3/4 Inches Length Pack of 14

Product Description

The Diversitech 6641 Hex Head Cap Screws are a pack of 14 fasteners designed for reliable use in HVAC, plumbing, and general mechanical applications. These screws feature a 3/8 inches 16 thread size and a 3/4 inches length, making them a standard choice for securing equipment brackets, mounting hardware, and structural components in both ducted and ductless HVAC systems. Manufactured from low carbon, Grade 2 steel, the 6641 screws meet USS classification standards, ensuring consistent dimensional accuracy and load-bearing performance across a wide range of trade applications. The hex head design allows for fast installation and removal using standard wrenches or sockets, which is a practical advantage for HVAC technicians, plumbers, and mechanical contractors working in tight spaces or on high-volume service calls. The total thread length on each screw equals two times the diameter plus 1/4 inches, following standard partial-thread hex cap screw geometry. This threading profile provides strong clamping force and resistance to loosening under vibration, which is common in HVAC unit installations and equipment mounting. Grade 2 low carbon steel offers adequate tensile strength for light to medium duty fastening tasks while remaining easy to work with in the field. The 14-piece pack format is well suited for both single-job use and small inventory restocking. HVAC installers and service technicians rely on consistent fastener packs like the Diversitech 6641 to keep jobs moving without searching for individual hardware. These hex cap screws are compatible with standard 3/8 inches 16 UNC threaded holes and nuts, which are among the most common thread patterns found in HVAC equipment mounting frames, air handler bases, condenser pads, and related structural hardware.

• 3/8 inches 16 thread size with 3/4 inches length for standard HVAC and mechanical fastening
