    Reach Recessed 13mm Fasteners Without Losing Grip

    Reach Recessed 13mm Fasteners Without Losing Grip

    This extra-long 250mm extension universal socket combines reach + articulation so you can get on 13mm fasteners that sit behind brackets, frames, lines, or housings. The 6-point profile helps reduce corner rounding, and the magnetic nut grip helps hold the fastener during removal/installation when you’re working blind.

    Best Use Cases

    • Recessed 13mm bolts/nuts behind guards, brackets, and frames
    • Hose clamps/brackets and accessory fasteners where a straight extension won’t line up
    • Tight swing areas where you need reach first, then angle into the fastener

    Why This Style Works

    • Extra-long 250mm reach reduces the need to stack multiple extensions
    • Universal-style articulation helps you line up from an offset approach
    • Magnetic nut grip helps prevent dropped hardware in engine bays and undercarriages
    • 6-point opening for a more secure bite on hex fasteners
