Custom Vented A354 BD Socket Head Screws With Drilled Hole

 

These custom vented socket head screws were manufactured for our aerospace customer using A354 Grade BD material with MIL-DTL-13924 black oxide finish.  5/16-24 UNF was rolled to a length of .625 inches and the head was cold formed with drawing specified markings.  A hole was drilled through to vent the parts at a diameter of .152 +.004/-.001" and a .063" hole was drilled across the thread.  The drilled holes created burrs, especially at the drilled hole area on at the threaded end, which made these parts very tricky and time consuming to get perfectly right.

Custom Flat Head Breakaway Screws

 

These custom breakaway screws are manufactured domestically in the USA for our aerospace customer using 303 stainless steel material with zinc nickel plating and black topcoat.  Threebond thread locking patch is applied on the flat head screw to complete the parts.  The breakaway section also incorporates a hex socket recess drive to allow for faster and easier assembly.  The cosmetic finish on the parts is not perfect due to the top coat getting nicked during the transport and patch application process.  The high level of corrosion resistance however and mechanical properties are unaffected.

Custom Aluminum Button Socket Vented Screws

 

These custom vented button head screws were manufactured for our automotive trailer manufacturing customer using 6061 aluminum material with 10-32 cut thread measuring .313 inches in length below the head.  Certs were included with the parts.

Custom ASTM A564 Socket Shoulder Bolts

 

These custom ASTM A564 Gr 630 H1150 socket head shoulder bolts were manufactured for our energy sector OEM customer using DFARS compliant raw material with the final parts age hardened at 1150F to achieve28-37 HRC.  The parts were fully machined with 3/8-16 UNC-2A cut thread and .375" across the flats hex recess.  The head measured .750" in diameter and .460" in height.  Overall length of the part underneath the head measured 2.75 +/-.010.  Full certs were provided with the parts.

Custom Oval Head Shoulder Screws

 

These custom oval head shoulder screws were manufactured for our electronics customer using 18-8 stainless steel material with partial rolled thread and a 12.5 degree tapered point to allow for faster installation times.  The 1/4-20 UNC 2B rolled thread was set to a length of 1.000" and the overall length under the head was at 2.500".  The head diameter was dialed in to .370" and head height to .170", with a cold formed #3 phillips drive.  Full certs were provided with the parts.

Custom Grade 5 Flat Head Wood Screws

 

These custom wood screws were manufactured using Grade 5 10B21 steel material with electro zinc + clear finish.  They were heat treated to achieve HRC 25-33 hardness prior to the plating process.  The partial thread was rolled and the overall length of the screw inclusive of the slotted flat head was set to 4 inches.

Custom Automotive Alloy Steel T-bolts

 

These custom T-bolts and shoulder T-bolts were manufactured for our automotive customer using AISI 4140 alloy steel material with commercial black oxide finish.  1/4-20 thread was rolled on both versions pictured here and the overall length under the head ranges from 1.075" to 1.200".  Full certs were available with the parts.

Custom Metric Torx Button Flange Screws

 

These custom metric torx button flange screws were manufactured for our electronics manufacturing customer using AISI 1018 steel material with a zinc clear finish.  M3 X 0.5MM thread was rolled under the head and blue nylok patch was applied after the zinc clear plating to finalize the parts.  T10 torx drive was cold formed on the head and the washer head OD was set to 7.5-8.0MM.

Custom Stainless Screws With Socket Drive Point

 These custom smooth round head screws were manufactured for our gun manufacturing customer using 304 stainless steel material with a cold formed drive-less head and M2.5 X .45MM rolled thread.  A .050" hex recess drive was broached at the end of the threaded point.  Full certs were provided with the parts and the parts came with a factory passivated finish.

Custom Stainless Barrel Nuts and Barrel Bolts

 

These custom stainless steel barrel nuts and barrel bolts were manufactured for our aluminum extrusion manufacturing customer.  304 stainless steel material was used with factory passivation finish and 1/4-20 matching thread.  The socket head screws were 1-1/2" in length under the head and the barrel nuts had internal thread depth at 10mm min.  Both parts were kitted to our customer specifications.
