Battery Operated Clock Mechanism Replacement Kit, Silent Quartz Clock Movement with Hands...

Dimensions: 1/4 in (0.236 in / 6 mm) thread length, 1/2 in (0.512 in / 13 mm) overall shaft length. Thick Shaft - Hour hand shaft diameter 7/32 in (0.217 in / 5.5 mm); Minute hand shaft diameter 9/64 in (0.142 in / 3.6 mm); Second hand shaft diameter 0.035 in / 0.88 mm; Thread diameter 5/16 in (0.299 in / 7.6 mm). If your original mechanism has a 1/4 in (0.236 in / 6 mm) thread length and with thick shaft, we suggest that you simply select the same size. Clock Dial Compatibility: This short shaft clock mechanism fits thin panels precisely. The maximum compatible clock dial thickness is 1/8 in (3 mm). Recommended for clock panels with thickness between 1/32 in - 1/8 in (1 mm - 3 mm). For panels thinner than 1/32 in (1 mm), use more rubber washer or other gasket to add thickness for a secure fit. If your panel exceeds 1/8 in (3 mm), you must choose a longer shaft mechanism. Please carefully measure your dial thickness with a caliper before ordering to avoid returns. Critical 1/8 in (3 mm) Safety Rule: The mounting hardware requires 1/8 in (3 mm) of thread length to fully engage and secure the movement. Therefore, the thread must be at least 1/8 in (3 mm) longer than your panel thickness. This mechanism has a 1/4 in (6 mm) thread - after subtracting the 1/8 in (3 mm) safety margin, the maximum panel thickness is 1/8 in (3 mm). If your clock panel exceeds 1/8 in (3 mm), the tighten hex nut will not reach the threads and your mechanism will not stay in place. Thick Mounting Hole Compatibility: This quartz clock movement replacement kit is designed for clock hands with thick mounting hole. Hour hand mounting hole 7/32 in (0.217 in / 5.5 mm); Minute hand mounting hole 9/64 in (0.142 in / 3.6 mm); Second hand mounting hole 0.035 in / 0.88 mm. If you want to reuse your own clock hands, you must ensure that their mounting holes fit MCDFL clock mechanism shaft size listed above. Using incompatible hands will cause loose fit or installation failure. Our clock movement kit comes with 3 set of small clock hands. These hands work perfectly for 3-3/4 in - 6 in (95 mm - 152 mm) small wall clock, desk clock, mantel clock, bedside clock, and mini clock.
