    Rated 1 out of 5 by from not the part pictured When I went to collect the part, is was not the M8 bolt I expected but was shorter and wider than the one pictured and so I had a wasted journey. The website itself did not specify, but pictured the correct thing. One of the reviews said it was indeed M8, but in the shop it wasn't.

    Rated 3 out of 5 by from Replacement of failed crank retaining bolt The bolts were used to replace an M8 with 1.0mm pitch crank arm retaining bolt that had failed catastrophically whilst bicycle was in use. The failed bolt had probably been over tightened and a fatigue crack developed. The broken bolt was extracted from the bottom bracket made by shimano. I could not get the bottom bracket out to identify it due to a stripped thread. Halford could give a better description of this product and describe compatibility, I took a punt on these bolts since it was difficult to find items described in enough detail to warrant online purchase. It was guessed that the bolts were probably a common standard used on commonly equipped bicycles. Regarding quality ; until the item has seen service I am relying on Halford to supply a part that Is fit for purpose so I cannot rate it other than average. Despite some reservations, well done Halford for bothering to stock a useful generic part. The excellent rating arises as I got what I was looking for at short notice and could pick up a solution to a problem.

    Rated 5 out of 5 by from Replacement bmx crank bolt This item is generally not on show so check the "available in store" and then ask the staff to search out the back! Great replacement crank bolt, fits We The People etc (think its 19mm - the visible hex part on show is silver not black)

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
