Case celebrated the 10th Anniversary of the CopperLock in 2007. This pattern was retired to the Case XX Vault in July 2008. The SlimLock. The SlimLock was originally produced in 2005 as a tribute to John Russell Case. Each knife carries a "JRC" (John Russell Case) tang stamp and a liner that locks. The first featured BG-42 steel blades.
The bolt/nut structural latch and 4-bar capture latches remained, although the bolt diameter had increased to 0.625 inches (15.9 mm). Both the bolts and the capture latches were motorized with manual backup being available, although the individual mechanisms were still driven by way of sealed couplings that passed through the bulkhead.
The screw itself should be drilled a minimum of 1" into the concrete to hold effectively and a maximum of 1-3/4" or the threads will wear and will lose holding power. Ideally 1-1/4" to 1-1/2" of screw thread in the concrete. [1] So for example, if a 1/2" board is being screwed onto the concrete, a 1-3/4" to 2" concrete screw should be used ...
The Thury thread form had the crests rounded at 1 / 6 p and the roots rounded at 1 / 5 p so the thread angle was close to 47.5° but not exactly. This was simplified in the BA thread definition by defining the thread angle to be 47.5° exactly and the thread form to be symmetrical with a depth of 3 / 5 p.
This standard defines property classes, the metric equivalent of a screw grade, that are almost identical to those defined by ISO 898-1, [2] except for the addition of the 8.8.3 and 10.9.3 classes. These two additional standards are fasteners that have the same mechanical properties as their base property class (i.e. 8.8 and 10.9), but are made ...
3. Flat washers with specified property classes [4] 5. Set screws and similar threaded fasteners not under tensile stresses [5] [6] 6. (Now withdrawn) Nuts with specified proof load values – Fine pitch thread [7] 7. Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm [8]
“A test like this is not complete if it’s positive and you have not had a colonoscopy.” This is the second blood test to screen for colon cancer; Epigenomics’ Epi proColon was approved in ...
Generally, the bolts are 15 to 22 inches long but the standard length is 20 inches. Experts recommend longer bolts [4] but they have certain disadvantages as well. The weight of the bolt can have a serious effect on the range of the bolt. The bolt's total weight includes the bolt's weight, nock, insert, vanes, and broadhead or field point.
