4BA, Cap Head, Socket Screw/ Allen Bolt, High Tensile (12.9), Self Colour.

Fixaball sells all lengths of 4BA socket cap screw/ bolts. 

The, ‘Socket Cap Screw/ Allen Bolt,’ term is used to describe a fastener that is either fully or partially threaded. A screw is fully threaded and a bolt is partialy threaded. Some engineers may call them screws if the person uses the shorter length range of sizes. The thread stays the same length as the fastener gets longer and the maximum length of thread is equal to 2.5 times the diameter (or thereabouts). ‘Socket,’ refers to the hexagon shaped indentation found on the top of the fasteners’ head. Here, you can use a hexagon key (Allen Key) to tighten and loosen the fastener. 'Cap' refers to the cylindrical shaped head.

 

Orders placed before 2pm are dispatched same day (Mon-Fri).

Standard, Free Delivery is Royal Mail, 2nd Class (2-5 days, most likely 2 days). For a faster delivery time, select 1st class or courier at checkout. 

Please make your size and pack quantity selection from the drop down menus at the top of the page.

My item is shown as delivered but it hasn't been?

What can I do if my item is shown as delivered, but it hasn’t been received?
If you’re the recipient:

Check whether the item was sent using a service that obtains a signature on delivery. If it was, do you recognise the name of the person who accepted the item? The name will be provided by the person who accepted the delivery and not always the person on the address label.
If the item was sent to your home, ask anyone else living there if they accepted the delivery. Please also check if the item has been left with a neighbour, or in your designated Safeplace if you have one.
If the item was sent to your work address, check with the post room and your colleagues to see if someone accepted the delivery.
If you bought the item online, check the shipping address was correct.

UPS - Packages over 2 kgs

We use UPS as our preferred courier. Please make sure all details of the address are included as courier drivers will not fill in the gaps, leading to long delays or even loss

 

Fixaball, International Orders.

Offshore and International Shipping

We use Royal Mail, Airmail, Tracked & Signed for international orders.  However, if the order exceeds the maximum weight (2kg) we will use UPS. Often, discounts can be offered on light weight/ high value goods if you email or call. Also, faster delivery can be arranged on your request.  The dispatch window for all of our offshore sales is 1 working day (most likely same day dispatch if ordered before 2pm).

Our delivery services are reliable; however, occasionally there may be a delay due to various unforeseen circumstances (weather, industrial action, holiday seasons). With this in mind, please consider feedback based on what we can control, which is our quick, dispatch time (same day if ordered before 2pm). Our aim is to do everything we can to support you.
