## Description

HHIP 6 X 6 X 2" Granite Surface Plate Grade B 0 Ledge The top surface of this plate is precision ground to achieve a high degree of flatness and the accuracy is +/-0001". It is a Grade B (Grade 1) plate. Granite surface plates meet or exceed Federal Specifications GGG-P-463C and it includes a certificate of inspection. (Note that these are not NIST traceable.) Granite plates are used for measuring the flatness and squareness of other objects, laying out parts, calibrating instruments, setting up tools, checking parallelism and perpendicularity, and measuring heights with the use of a height gage. They are also used as a work surface for assembling, inspecting, and marking parts. Non-magnetic and non-conductive. Surface plates are offered by HHIP in various sizes, with different levels of flatness and accuracy and are checked by an auto collimator for overall accuracy assurance.

## Questions & Answers

**Q: upon reading the certificate, i was just wondering what is the National Department of "Standays"? and what exactly is a "ladotory"?**
A: Hey thanks for these great questions while I’m not affiliated with this company I did buy this a few years ago and feel qualified to respond.
The National Department of Standays is an international compliance organization that helps determine when people should stand or sit.  Ever wonder why we stand at the National Anthem and sit on a bus, yep that’s the NDS.  Ladotories are quite common internationally and are laboratories where only dudes can work (lads).  While these facilities have produced some of the great 21st century inventions (Whoopie cushions, fart spray, gak) they are increasingly being called into question due to gender inequality and overall zaney antics.

**Q: I will need the 24” x 18”x 3” for my machine shop, I will use it for scraping surface. So it is really flat ?**
A: It's flatter than a concrete paver, but not as flat as a quality name brand (Starrett / Mitutoyo / StandRidge) granite surface plate. I would bet money these Chinese sourced granite plates are no where near meeting  actual "Grade A" specifications for flatness in the USA. (JMHO) I would not trust one to be my only master reference for scraping machine surfaces / ways / dovetails. I only use my HHIP plate for lapping small parts. I do all my metrology work on a Starrett Crystal Pink granite plate.

**Q: Are the sides of the surface plate square to the top?**
A: They are not made to a specific tolerance on the sides.  We  offer Precision Granite squares that have a squareness of +or - of 0.0001". Please see HHIP # 4901-2705 and HHIP# 4901-2706

**Q: Is this nist traceable?**
A: No. It's a product of China.
