SendCutSend is proud to use PEM(R) hardware.
Hardware insertion will add a $9 minimum to your cart total, and per-hole pricing will depend on the fastener selected and quantity.
When planning to place your order, keep in mind that hardware installation adds 1-3 business days to our normal processing times. Check out our Lead Times page for more information.
We currently offer seven materials in a variety of thicknesses for hardware installation:
All parts that have hardware installation included will need to meet certain size requirements in order to be manufactured correctly:
These are general size requirements for hardware insertion. Check the hardware catalog for each type of hardware below before submitting your order to make sure your parts meet all specifications.
Holes up to 4.00″ can be selected for hardware installation. When selecting holes for the desired hardware in your design, we will automatically resize the hole to the required size based on the hardware selected.
Please keep in mind that because they will resize, you will need to verify you have adequate clearance to other features and edges of the material. We list the minimum distance hole C/L to edge required for each PEM size in our hardware catalog. Measure from the center of the mount hole to the edge of adjacent cut features to ensure there is enough space.
Provide enough space between hardware and bends to prevent interference.
Calculate the minimum distance needed by adding the bend allowance/2 + minimum distance hole C/L to edge for the hardware size desired.
Confirm the bend allowance using our Bending Calculator. Input the material thickness and bend angle to find the correct bend allowance in the Advanced details. Confirm the minimum distance hole C/L to edge in our hardware catalog.
Then, measure from the center of the hardware mount hole to the center of the bend in your design to ensure the hardware is at least the minimum distance away from the bend.
We do not allow hardware installation on parts with acute bends. Contact our support team for questions.
Press fit nuts are internally threaded with a knurled outer diameter. Lightweight, simple, and able to withstand high pressure and high torque, press fit nuts are often found in flooring and aircraft applications.
Press fit nuts provide load-carrying threads in metal sheets that are too thin to be tapped.
Used to stand parts of an assembly off of each other, press fit or self-clinching standoffs have a wide range of applications. They provide secure fastening for delicate parts, with electrical components being the most widely used in conjunction with press fit standoffs. Press fit standoffs provide a threaded fastener that delivers uniform spacing between parts.
Also known as press fit studs, self-clinching studs are designed to be a permanent fastener in your assembly. Made to withstand high torque, stress, and weight environments, studs can be used in dozens of applications to increase the strength and longevity of your part.
Studs are typically used when it is inconvenient or impossible to access one side of a threaded joint or when there is not enough clearance around the joint to have a traditional nut/bolt on the material surface.
Though our standoffs and studs are technically flush, they may be raised .015″ depending on your material selections
When you have confirmed your part meets our geometry requirements and you’ve uploaded the file to our app, walk through the normal order process and select “Add Hole Operations.”
You’ll see a list of hole options which you can add hardware to, as well as a link to our catalog of hardware options. Select your desired hardware and size, and you’ll see it show up on the 3D preview of your part. Make sure the hardware is placed on the correct face (top or bottom). Click “Add to Cart” and the hardware will be included in your order.
If after reading these guidelines you’ve found you need to make some changes to your part design, check out our tutorials for designing and preparing your files in Illustrator, Inkscape, and Fusion 360.
We’re proud to be on the Inc. 5000 Fastest Growing Private Companies list. Thanks to our amazing customers and rock star team for enabling us to grow this fast. Keep creating!
