Grade 5 Threaded Rod Properties

Hdg threaded rods meet the chemical composition and mechanical property requirements of astm f1554.

Grade 5 threaded rod properties.

Astm a193 specification covers requirements for chemical composition mechanical properties hardness heat. Threaded rods are not included in the astm f1554 standard. Astm a354 is the classification for grade 8 threaded rod made of high strength steel quenched and tempered. Astm a193 grade b7 specification for high tensile bolts screws stud bolts threaded rods anchor bolts and other externally threaded fasteners made from heat treated chromium molybdenum alloy steel grades such as 4140 4142 4145 4140h 4142h and 4145h in sae aisi classification.

Astm a563 grade 0 1 4 1 1 2 69 000 52 000 b55 c32. The most common material for threaded rod is steel spanning a variety of alloys strengths and hardness. Technically all thread rod made from a36 steel should be ordered to a fastener specification such as a307 grade a a307 grade b or f1554 grade 36. Steel threaded rods can be coated or uncoated with zinc being a common coating for electro plated and hot dip galvanized threaded rod.

Mechanical properties of internally threaded fasteners plain galvanize coating 1 min. This chromium molybdenum steel has similar strength to sae grade 5 fasteners however it is specifically used in high temperature and pressure applications. This table shows the mechanical properties of b7 grade 5 and grade 8. Technically all thread rod made from a36 steel should be ordered to a fastener specification such as a307 grade a a307 grade b f1554 grade 36 or sae j429 grade 2.

It is classified as astm a449. 5 8 11 0 83 1810 1610 3 4 10 1 25 2710 2420 7 8 9 1 70 3770 3360 1 8 2 23 4960 4420 1 1 8 7 2 81 6230 5560 1 1 4 7 3 54 8000 7140 1 1 2 6 5 12 11630 10370 performance data grade a headed bolts threaded rods and bent bolts intended for general applications. It is also used as threaded rod in concrete and epoxy. However some companies stock all thread rod manufactured from a36 steel and can certify it as such upon.

The appropriate fastener specification will depend on the application. Threaded rod is produced from a variety of materials. The stronger and more heat resistant grade 5 threaded rod is made of medium carbon steel quenched and tempered. The appropriate fastener specification will depend on the application.
