    Rated 5 out of 5 by from wall mount samsung tv The perfect bolt for hanging Samsung tv on wall. A good quality bolt of the correct size which was difficult to find and only Halfords had the correct bolt.

    Rated 2 out of 5 by from Does not fit all makes This bolt may well be a suitable replacement for most seat post bolts but alas it did not fit mine. I have a "Giant" bike and the thread is the wrong size.

    Rated 5 out of 5 by from Bolt fix This bolt is robust and was quickly fitted to the bike. The existence obit's availability does not appear to be widely known. I visited three bike stores including a Halfords store before finding the bolt by persistent search on line.

    Rated 5 out of 5 by from Exactly what it says it is 1 X seat bolt fixed. Many other bike shops suggested that I buy a new seat stem! Not Halfords. They have the right part at a good price.

    Rated 5 out of 5 by from Top Quality Seat Attachment Fitting To be honest, I've not seen a bolt of this standard in any other retailer. The smooth chrome finish gives an understated look to a serious bit of fixing kit. The Allen key fixing orifice is exceptional. Strong, sturdy and reliable, this seatpost bolt is top of its class.

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.
