356 ESTIMATE OF WEIGHT AND COST 



costs of building hardware, lumber, etc. Prices of building hardware 

 are usually quoted at a certain discount from standard lists. These 

 standard lists and the discounts can be obtained from the 

 dealers, or the method described in the following paragraph may be 

 used. 



The following method of obtaining costs of building hardware 

 and other miscellaneous materials, has been found very satisfactory: 

 Obtain standard lists from the dealers, or a very complete one entitled 

 "The Iron Age Standard Hardware Lists" may be obtained from the 

 David Williams Co., New York, for $1.00, postpaid. To find the cur- 

 rent discount, consult the current number of the Iron Age, or a simi- 

 lar publication the Iron Age is published by the David Williams Co., 

 New York, at $5.00 per year, or 10 cents per single copy, and gives 

 each week the current hardware prices and discounts. By applying 

 the discount to the prices given in the standard lists the current price 

 of the material can be obtained. The standard lists of machine bolts, 

 carriage bolts, nails, and turnbuckles are given for convenience in es- 

 timating and to illustrate what is meant by lists. 



To illustrate the method just described the current prices (1903) 

 will be obtained for a few items : 



2-in. Barbed Roofing Nails. The base price of nails is $2.65 per 

 keg of 100 Ibs., and from standard nail list (Table XXVIII) we see 

 that 2-in. barbed roofing nails take $0.35 per 100 Ibs. advance over the 

 base price making the price $3.00 per 100 Ibs. 



Carriage Bolts. 2j^" x y 2 " carriage bolts are listed (Table 

 XXVIII) at $3.00 per 100, from which a discount of 60 and 10% 

 is allowed. A discount of 60 and 10% is equivalent to a discount 

 of 64%, making the price of the bolts $1.08 per 100. 



Machine Bolts. 4" x y 2 " machine bolts are listed (Table XXIX) 

 at $4.90 per 100, from which a discount of 65 and 5% is allowed. A 

 discount of 65 and 5% is equivalent to a discount of 66%%, making 

 the price of the bolts $i .36 per 100. The weight of machine bolts and 

 nuts is given, from which the price per Ib. can be obtained for any size 

 of bolt.
