Klein KNECT Ratcheting 9-in-1 Low-Profile Socket Wrench Set (65430LP)

Key Features
Flex Head Pass-Through
The pass-through ratchet head drives hex nuts on long threaded rod and bolts, and the flex head locks in at least 11 positions for angled access.
Low-Profile Sockets
Reduced socket height gets the ratchet onto fasteners where standard sockets stack up too tall.
MODbox Case
The set stores in a MODbox accessory case that connects with other Klein MODbox cases.
Overview
The Klein Tools KNECT Ratcheting 9-in-1 Low-Profile Socket Wrench Set (65430LP) pairs a flex head pass-through ratchet with eight SAE low-profile impact sockets. This is a pass-through socket wrench set designed for tight-clearance fastening, such as hex nuts on threaded rod and long bolts, and equipment fasteners where a standard ratchet and socket do not fit.
The eight sockets cover 1/4", 9/32", 5/16", 11/32", 3/8", 7/16", 1/2" and 9/16". Because the head is pass-through, the bolt or threaded rod can extend through the socket and ratchet, so you are not limited by socket depth on long studs.
The flex head locks in a minimum of 11 positions for angled access, and the low-profile sockets have reduced height for confined areas. Together they let you work fasteners close to walls, inside cabinets and behind equipment.
Sockets are cold-forged chrome-molybdenum (Cr-Mo) steel with a manganese phosphate finish and are impact-rated for high-torque applications. Color-coded rings with laser-etched size markings make the right socket easy to find. All sockets are 6-point.
The set integrates with KNECT (M) multi-functional adapters for more versatility, and the MODbox accessory case connects with other MODbox cases for jobsite organization. Klein lists a 3/8" drive size and a weight of 1.6 lb (0.7 kg); the case is about 9-1/4" x 1-13/16" x 3-3/4" (23.5 x 4.6 x 9.4 cm).
Who should buy it: electricians, mechanical and HVAC installers who spend their day on threaded rod and tight-clearance SAE fasteners.

Pro Tip
On long threaded rod, run the nut down with the rod passing through the head instead of stacking a deep socket. It is faster, and the low-profile setup stays tight to the surface when you finish.
Tool Nut's Take
Threaded Rod's Best Friend
The Klein Tools KNECT Ratcheting 9-in-1 Low-Profile Socket Wrench Set (65430LP) puts eight SAE sizes on a flex head pass-through ratchet that fits where standard sockets will not.
Who it's for: Electrical and mechanical trades working on threaded rod and tight-clearance fasteners.
Why it stands out: Pass-through head, low-profile impact sockets, 11-position flex head and MODbox storage.
Worth knowing: SAE only. If you also need metric, the 17-in-1 set (65431LP) adds 7 mm through 14 mm.
Common Questions
What sizes are in the Klein 65430LP? 1/4", 9/32", 5/16", 11/32", 3/8", 7/16", 1/2" and 9/16" SAE low-profile sockets.
What does pass-through mean? The bolt or threaded rod can pass through the socket and ratchet head, so long studs do not limit how far the nut can travel.
Are the sockets impact-rated? Yes. They are cold-forged Cr-Mo steel and impact-rated.
Does it come with a case? Yes, a MODbox accessory case.
