  • Titanium per ASTM B348 - Q: What makes Titanium fasteners per ASTM B348 unique? A:  ASTM B348 is a specification that applies to pure titanium grades 1-4 as well as alloyed grade 5 and 23 titanium. The spec refers to requirements for hot or cold worked bars from which bolts and threaded rod are made. Titanium bolts per […]
  • 17-4 Bolts to Replace 12.9 Zinc Coated Bolts - Q:  We are trying to move away from zinc plated 12.9 bolts due to hydrogen embrittlement problems and the geomet finish is giving us problems due to the diameter of the screw. As a better solution, we have thought about using Super Duplex screws or Nimonic 80A screws.  I understand that […]
  • Hastelloy Bolts Used in H2SO4 - Q: We are in search for a bolt material that can handle sulfuric acid – compatible with 96% H2SO4. The exposure should be low and only on an infrequent basis. Also,  these applications when H2SO4, DI Water is used to flush and clean off the surfaces during any maintenance that occurs inside the […]
  • High Strength Stainless Steel Lock Nuts - Q: We are essentially having issue identifying the highest available high strength stainless steel nylon insert nuts. Is Duplex 2205 the best option? A: If you are just looking for strength for your lock nut with a nylon insert, one of the highest strength stainless steel’s you could consider would be 17-4 PH […]
  • Fast Delivery for 1300C and Low Load Strength - Q: I’m looking to purchase some ¼-20 bolts/nuts/washers that will be suitable to fasten metal plate together at 1,300C.  The fasteners need to last at least 4 minutes at this temperature but preferably longer. The load on the bolts will be very low. A: I think there are a couple […]
  • Inconel 718 per AMS 5962 - Q: What is the difference between “standard” Inconel 718 and Inconel 718 per AMS 5962 A:  While nothing about Inconel 718 is standard, however the most popular variety of Inconel 718 bolts is per ASTM B637.  For this version of s, the bolts are age hardened to have a minimum […]
  • Aluminum 7075 for Lightweight Strength - Q: Why is Aluminum 7075 often used for aircraft? A: There are many grades of aluminum bolts but those categorized under grade 7075 are specifically used for aerospace and other high stress structural applications that require a combination of strength and extreme light weight. Grade 7075 can be tempered to different conditions, […]
  • Aluminum 7075 Compared to Titanium - Q: How does Aluminum 7075 compare to titanium grade 5? A: Aluminum 7075 can be tempered to many different strengths. The strongest being T6 which not only offers the highest strength. The primary drawback being that it also has low fracture toughness. Aluminum 7075-T6 bolts offer more strength than grade 2 titanium, […]
  • PEEK: Non-Conductive Bolts for up to 500F - Q: We are looking to find an electrically   non-conductive bolt that would also work at temperatures up to 500 F max. They will be used for an electrically live part isolation kit. Anything that will fit the bill? A: Without any understanding of your strength requirements, and focusing solely on the […]
  • Monel 400 Bolts per ASTM B164 - Q: What does the spec ASTM B164 apply to and can you produce hex heads per this spec? I believe it is for Monel bolts? A: Monel bolts per ASTM B164 applies to both Monel 400 and Monel grade 405. This specification standardizes the different processing techniques for each of these materials […]
