theis Report post Posted July 14, 2010 I'm trying to find the screw post that have the little self piercing points on them so that when you tighten the Chicago screw it pulls the little spikes into the leather.I have searched the net and I can't locate them, maybe it is because I don't know their proper name. thanks Tommy Quote Share this post Link to post Share on other sites
Luke Hatley Report post Posted July 14, 2010 YOU'LL be amazed at the sizes your local hardware store sells, Home Depot or Lowes has them. Quote Share this post Link to post Share on other sites
particle Report post Posted July 14, 2010 The word you're looking for is "T-Nut". As Luke said, you can find them in small quantities at the local home store - Lowes, Home Depot - look at the isle that has all the pull-out draws with specialty fasteners. That being said, there is a version with the barbs, and there is a version with tiny holes that you would nail a brad through to hold the fastener to a piece of wood. I have been unable to find a t-nut with short enough barbs that won't completely penetrate the leather without being filed down to a shorter length. If anyone knows where to find the t-nut with barbs that won't penetrate 6-7 oz leather, I'm all ears. Quote Share this post Link to post Share on other sites

T-Nuts consist of a flat flange with a cylindrical barrel which is threaded to allow a bolt to engage the T-Nut. Prongs often extend from the flange to grip the material into which the T-Nut is being inserted. Thread Sizes: 4-40 to 5/8-11 Metric: Available Barrel Heights: 1/8" to 7/8" Closed End T-Nuts Provide maximum thread engagement and positive bolt stop. Prongs provide higher retention and reduce push out. Large flange prevents pull throughLocking T-Nuts provide an economical alternative to patch lock in blind applications. Entry torque is typically 8-12 in-lbs, custom torque requirements are available. Available in hand driven or production maximizing hopper feed styles.3 Prong T-Nuts are used primarily in hard materials to minimize splitting caused by prongs. Also see Propell Nuts if splitting is a problem.4 Prong T-Nuts can be used in hard and soft woods. Also available in Hopper Feed Style for labor-saving automation.6 Prong T-Nuts can be used primarily in soft woods, particleboard, plywood and softer plastics. Good retention.Stafast's Hopper Feed T-Nuts offer high retention and reliable entry which reduces labor and rework costs. These T-Nuts can be automatically machine inserted straight, flush, and ready for production assembly.Also see "Ultimate" T-Nut T-Nut Automation Equipment Stainless Steel T-Nuts Standard hand driven T-nuts or Hopper Feed T-Nuts are offered in 304 Stainless Steel for marine or corrosion resistant applications. Stainless Steel T-Nuts are excellent for fastening metal to wood or plastic, or for anchoring wooden components together. Propell Nuts - Steel and Stainless Steel The deep skives provide excellent retention for blind and end-grain applications such as glides, levelers, wood turnings, or hard material applications that may split with regular prong type T-Nuts. Also popular in hard plastic applications. Thread Sizes: 8-32 to 5/8-11 Metric: Available Barrel Heights: 1/4" to 7/8" Quote Share this post Link to post Share on other sites
TwinOaks Report post Posted July 15, 2010 I've found the easiest way to prevent the prongs from going through the top layer of leather is to double snip them with a set of dikes. First cut is diagonal on the spike, parallel to the edge to reduce height, second cut is across the bottom to free the piece you trimmed. Or, alternately, just snip the point off at the appropriate height- I've never had a problem with the non-pointed spike penetrating a layer of leather to hold it in place.
