These custom internally threaded square pins were manufactured using 12L14 square bar stock material - sharp corners were absolutely critical and initial trial runs with alternative material options were unsuccessful until we finally found square bar material measuring very close to .69" across the corners. The sharp corners allow the pins to lock at the remaining .14" long shoulder seen on the parts.
-
We had approximately 10,000 pieces of these custom large stainless steel pins manufactured for a customer installation in Italy. 303 stainless steel was used for production and the pins measured .249" in diameter by 5" in overall length.

Width across the flats on the hex measures .250 inches.
-
We provide our customer a small batch of these custom stainless steel double end studs at just over 100 pieces. They wanted to replicate existing parts but did not have any drawings or prints. We used a sample piece provided to replicate all dimensions to a +/-.01" tolerance. 1/4-20 thread is incorporated on the larger diameter side and 10-32 on the other, with approximately half the thread turned down into a dog point.
-
These are custom stainless tamper proof sheet metal screws measuring 6-18 X 1/2 inch in length. A tamper resistant one way oval head is incorporated with type A sheet metal screw thread. We have these parts manufactured domestically at 30,000 to 50,000 pieces and release them to our customer as needed throughout the year. 18-8 stainless steel material is used on these specific one way oval screws but we also supply an identical part in 316 stainless steel material.
-
These custom stamped L brackets are made using low carbon steel material with zinc plated finish. .125" thick material is used and the outside dimensions are 3/4" for each leg, as well as the width of the bracket length itself. Production takes place in the USA and we typically run approximately 10,000 pcs at a time for this stamped part. Our customer uses it in combination with two other custom stamped brackets used to assemble decorative paneling.
-
These are 8-32 custom V bolts we had domestically produced for our customer. Initially 12 pieces were run for prototype testing purposes prior to full production order. The inside length to the bottom of the V is 1" and .625" between the legs. 0.6" of 8-32 thread is incorporated on both legs. One thing to note with this type of bent part is that the threaded areas are clamped during the bending process - at minimum this results in a small visual dent in the threads and at worst, if over clamped the thread can be damaged to the point of creating issues running the mating parts. We carefully inspect the parts to make sure this latter issue is avoided. Unfortunately, there is no way to completely avoid grabbing on to the threaded areas for mass production that we have seem, without of-course limiting the amount of thread on each leg.
-
These custom sharp point wood screws were manufactured domestically using case hardened steel material with zinc bake and yellow finish. A high hex washer head was incorporated without serrations and full #12-11 thread at 1-3/4" in length under the head. A narrow angle was incorporated for the point that together with a type 17 feature created an extra sharp point to allow for automated feeder systems in our customer's application.
-
Custom brown painted self drilling screws in 18-8 stainless steel material supplied to our long time customer at 10,000 pcs per release. We typically stock these parts based on revolving 12 month blanket purchase order arrangements - pricing is locked in based on 100K pieces but parts are released on a monthly schedule based on our customer's seasonal need. The sealant on the brown painted heads was set to flat sheen as our customer prefers to avoid glossier finishes. Lead time for painted parts at these quantities is typically 3-4 weeks from the procurement of the plain version.
-
This is a special partially threaded machine screw supplied to our customer at 30,000 pieces. The part is made using 18-8 stainless steel and is slightly tapered at the point to allow for faster use in the customer's application. The head is a slightly off-standard pan head with a phillips drive. Parts are made in the United States.
-
This is a special phillips flat DIN965 machine screw measuring M3 X 0.5 X 9MM and manufactured in the USA using steel with zinc plating finish. These parts we typically supply to our customer with a production run for each order at the quantity requested, typically around 3,000 pieces. While a variety of M3 X 0.5 DIN965 screws are available as standards, the 9MM length is often an impossible item to find off the shelf and requires production as a special.
-
We had 500 pieces of these large custom locating dowel pins manufactured domestically in alloy steel material, with heat treat to achieve 47-58 HRC core hardness. The original drawings were fairly aged and it was difficult to figure out how the transition point between the round and hex portions of the pins should be formed. We ended up producing samples with two different alternative interpretations and allow the customer to test for the ideal option pictured here. The round portion of the pin has a diameter of .625" + .0003"/-0" while the hex portion across the flats had to meet .7497 +.0002"/-0". Overall length was set to 1.4375".
