Hey Ken from ARUP-- We go to the hardware store and pick various sizes of large-headed bolts. The threads are nice to grip with gloved hands and stay cool as they're taller than the tamper backs. The heads are thick and hold a nice bit of heat, and with all the different sized we can pick what works for each specimen. At about $0.15 each--no one freaks out if they are accidentally discarded. Hope this helps or at least made you smile. Cheryl Cheryl Kerry, HT(ASCP) Full Staff Inc. Staffing health care professionals, one GREAT fit at a time. 800.756.3309 _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
