Murray 1960521sm Push Nut 0.156 Inch Diameter

Product Description

The MURRAY 1960521sm is a push nut fastener designed for secure, tool-free retention on shafts and studs measuring 0.156 inches in diameter. Push nuts work by pressing onto a smooth or threaded shaft, with internal teeth that grip and resist pull-off forces. Once seated, the fastener locks in place without the need for threading or additional hardware. This type of fastener is commonly installed by small-engine mechanics, outdoor power equipment technicians, and experienced DIYers performing maintenance or repair work on Murray lawn and garden equipment.

This push nut is suited for use in lawn and garden equipment applications where a low-profile, permanent or semi-permanent retention solution is needed on a 0.156-inch diameter shaft. Typical installation scenarios include securing wheels, pulleys, levers, and linkage components on walk-behind mowers and related outdoor power equipment. It is an OEM-sourced replacement part for Murray equipment requiring this fastener specification.

Installation Notes

Push nuts are installed by small-engine technicians or qualified service personnel. Before replacing any fastener on powered equipment, disengage the blade, remove the ignition key, and disconnect the spark plug wire to eliminate the risk of accidental startup. Press the nut squarely onto the shaft using a suitable socket or press tool until fully seated against the retaining surface. Note that push nuts are generally considered single-use fasteners and should be replaced rather than reused once removed.
