Tekton SIA13100 Impact Reducer 3/8 in F to 1/4 in M

Product Description

The TEKTON SIA13100 is a 3/8 inch drive (female) to 1/4 inch drive (male) impact reducer designed to connect impact wrenches and impact drivers to smaller-drive sockets and accessories. The adapter features square drive ends on both sides and a manganese phosphate finish over steel construction, providing corrosion resistance and durability in high-torque impact applications. At 1 inch in overall length and 0.09 pounds, it is compact enough for tight work areas. HVAC technicians, plumbers, electricians, and other trade professionals use this type of adapter when switching between drive sizes on the fly without changing tools.

This impact reducer is suited for use in residential and commercial service work where a 3/8 inch drive impact tool needs to accept 1/4 inch drive sockets or bits. It is particularly useful in panel work, equipment rooms, and mechanical spaces where multiple fastener sizes are encountered in a single job and tool changes slow down the workflow. The steel construction with manganese phosphate finish holds up to repeated impact cycles.

Key Features

• Reduces 3/8 inch female square drive to 1/4 inch male square drive for impact tool compatibility
• Steel construction with manganese phosphate finish for corrosion and wear resistance
• Compact 1 inch overall length fits in tight spaces
• Rated for impact use - not a standard hand-tool-only adapter
• Lifetime warranty from TEKTON

Compatibility

Designed for use with 3/8 inch drive impact wrenches and impact drivers accepting standard square-drive accessories, allowing connection to 1/4 inch drive sockets and attachments.

Installation Notes

This adapter is installed and removed by hand - no tools required. Ensure the adapter is fully seated in both the drive tool and socket before applying impact force. Inspect the adapter periodically for cracks or deformation, and replace if wear is visible. Use only with impact-rated sockets and accessories.
